Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998424, here are decompositions:
- 5 + 998419 = 998424
- 13 + 998411 = 998424
- 43 + 998381 = 998424
- 47 + 998377 = 998424
- 71 + 998353 = 998424
- 113 + 998311 = 998424
- 137 + 998287 = 998424
- 151 + 998273 = 998424
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 998,424 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 998424 first appears in π at position 951,192 of the decimal expansion (the 951,192ordinal-suffix:nd 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.
