Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724672, here are decompositions:
- 23 + 8724649 = 8724672
- 29 + 8724643 = 8724672
- 31 + 8724641 = 8724672
- 41 + 8724631 = 8724672
- 53 + 8724619 = 8724672
- 71 + 8724601 = 8724672
- 83 + 8724589 = 8724672
- 113 + 8724559 = 8724672
Showing the first eight; more decompositions exist.
