Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498440, here are decompositions:
- 31 + 498409 = 498440
- 37 + 498403 = 498440
- 43 + 498397 = 498440
- 73 + 498367 = 498440
- 79 + 498361 = 498440
- 97 + 498343 = 498440
- 109 + 498331 = 498440
- 139 + 498301 = 498440
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 498,440 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 498440 first appears in π at position 419,916 of the decimal expansion (the 419,916ordinal-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.
