Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72804, here are decompositions:
- 7 + 72797 = 72804
- 37 + 72767 = 72804
- 41 + 72763 = 72804
- 71 + 72733 = 72804
- 97 + 72707 = 72804
- 103 + 72701 = 72804
- 131 + 72673 = 72804
- 157 + 72647 = 72804
Showing the first eight; more decompositions exist.
