Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72774, here are decompositions:
- 7 + 72767 = 72774
- 11 + 72763 = 72774
- 41 + 72733 = 72774
- 47 + 72727 = 72774
- 67 + 72707 = 72774
- 73 + 72701 = 72774
- 101 + 72673 = 72774
- 103 + 72671 = 72774
Showing the first eight; more decompositions exist.
