Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72744, here are decompositions:
- 5 + 72739 = 72744
- 11 + 72733 = 72744
- 17 + 72727 = 72744
- 37 + 72707 = 72744
- 43 + 72701 = 72744
- 71 + 72673 = 72744
- 73 + 72671 = 72744
- 83 + 72661 = 72744
Showing the first eight; more decompositions exist.
