Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998738, here are decompositions:
- 109 + 998629 = 998738
- 199 + 998539 = 998738
- 211 + 998527 = 998738
- 241 + 998497 = 998738
- 409 + 998329 = 998738
- 457 + 998281 = 998738
- 541 + 998197 = 998738
- 571 + 998167 = 998738
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 998,738 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 998738 first appears in π at position 235,777 of the decimal expansion (the 235,777ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
