Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724492, here are decompositions:
- 5 + 8724487 = 8724492
- 13 + 8724479 = 8724492
- 31 + 8724461 = 8724492
- 71 + 8724421 = 8724492
- 163 + 8724329 = 8724492
- 173 + 8724319 = 8724492
- 181 + 8724311 = 8724492
- 191 + 8724301 = 8724492
Showing the first eight; more decompositions exist.
