Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742600, here are decompositions:
- 23 + 8742577 = 8742600
- 29 + 8742571 = 8742600
- 59 + 8742541 = 8742600
- 71 + 8742529 = 8742600
- 89 + 8742511 = 8742600
- 101 + 8742499 = 8742600
- 103 + 8742497 = 8742600
- 107 + 8742493 = 8742600
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 8,742,600 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
