Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998242, here are decompositions:
- 5 + 998237 = 998242
- 23 + 998219 = 998242
- 29 + 998213 = 998242
- 41 + 998201 = 998242
- 131 + 998111 = 998242
- 173 + 998069 = 998242
- 233 + 998009 = 998242
- 251 + 997991 = 998242
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 998,242 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 998242 first appears in π at position 969,611 of the decimal expansion (the 969,611ordinal-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.
