Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498442, here are decompositions:
- 3 + 498439 = 498442
- 41 + 498401 = 498442
- 233 + 498209 = 498442
- 353 + 498089 = 498442
- 389 + 498053 = 498442
- 443 + 497999 = 498442
- 449 + 497993 = 498442
- 479 + 497963 = 498442
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 498,442 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 498442 first appears in π at position 674,637 of the decimal expansion (the 674,637ordinal-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.
