Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72966, here are decompositions:
- 7 + 72959 = 72966
- 13 + 72953 = 72966
- 17 + 72949 = 72966
- 29 + 72937 = 72966
- 43 + 72923 = 72966
- 59 + 72907 = 72966
- 73 + 72893 = 72966
- 83 + 72883 = 72966
Showing the first eight; more decompositions exist.
