Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72768, here are decompositions:
- 5 + 72763 = 72768
- 29 + 72739 = 72768
- 41 + 72727 = 72768
- 61 + 72707 = 72768
- 67 + 72701 = 72768
- 79 + 72689 = 72768
- 89 + 72679 = 72768
- 97 + 72671 = 72768
Showing the first eight; more decompositions exist.
