Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72690, here are decompositions:
- 11 + 72679 = 72690
- 17 + 72673 = 72690
- 19 + 72671 = 72690
- 29 + 72661 = 72690
- 41 + 72649 = 72690
- 43 + 72647 = 72690
- 47 + 72643 = 72690
- 67 + 72623 = 72690
Showing the first eight; more decompositions exist.
