Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72750, here are decompositions:
- 11 + 72739 = 72750
- 17 + 72733 = 72750
- 23 + 72727 = 72750
- 31 + 72719 = 72750
- 43 + 72707 = 72750
- 61 + 72689 = 72750
- 71 + 72679 = 72750
- 79 + 72671 = 72750
Showing the first eight; more decompositions exist.
