Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72846, here are decompositions:
- 23 + 72823 = 72846
- 29 + 72817 = 72846
- 79 + 72767 = 72846
- 83 + 72763 = 72846
- 107 + 72739 = 72846
- 113 + 72733 = 72846
- 127 + 72719 = 72846
- 139 + 72707 = 72846
Showing the first eight; more decompositions exist.
