Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72762, here are decompositions:
- 23 + 72739 = 72762
- 29 + 72733 = 72762
- 43 + 72719 = 72762
- 61 + 72701 = 72762
- 73 + 72689 = 72762
- 83 + 72679 = 72762
- 89 + 72673 = 72762
- 101 + 72661 = 72762
Showing the first eight; more decompositions exist.
