Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998748, here are decompositions:
- 5 + 998743 = 998748
- 11 + 998737 = 998748
- 31 + 998717 = 998748
- 59 + 998689 = 998748
- 61 + 998687 = 998748
- 67 + 998681 = 998748
- 97 + 998651 = 998748
- 131 + 998617 = 998748
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 998,748 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 998748 first appears in π at position 32,300 of the decimal expansion (the 32,300ordinal-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.
