Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71724, here are decompositions:
- 5 + 71719 = 71724
- 11 + 71713 = 71724
- 13 + 71711 = 71724
- 17 + 71707 = 71724
- 31 + 71693 = 71724
- 53 + 71671 = 71724
- 61 + 71663 = 71724
- 127 + 71597 = 71724
Showing the first eight; more decompositions exist.
