Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498720, here are decompositions:
- 29 + 498691 = 498720
- 31 + 498689 = 498720
- 41 + 498679 = 498720
- 67 + 498653 = 498720
- 73 + 498647 = 498720
- 107 + 498613 = 498720
- 109 + 498611 = 498720
- 137 + 498583 = 498720
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 498,720 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 498720 first appears in π at position 1,509 of the decimal expansion (the 1,509ordinal-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.
