Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998258, here are decompositions:
- 61 + 998197 = 998258
- 97 + 998161 = 998258
- 181 + 998077 = 998258
- 229 + 998029 = 998258
- 241 + 998017 = 998258
- 367 + 997891 = 998258
- 379 + 997879 = 998258
- 577 + 997681 = 998258
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 998,258 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 998258 first appears in π at position 42,794 of the decimal expansion (the 42,794ordinal-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.
