Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724924, here are decompositions:
- 41 + 8724883 = 8724924
- 53 + 8724871 = 8724924
- 97 + 8724827 = 8724924
- 137 + 8724787 = 8724924
- 211 + 8724713 = 8724924
- 227 + 8724697 = 8724924
- 281 + 8724643 = 8724924
- 283 + 8724641 = 8724924
Showing the first eight; more decompositions exist.
