Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72770, here are decompositions:
- 3 + 72767 = 72770
- 7 + 72763 = 72770
- 31 + 72739 = 72770
- 37 + 72733 = 72770
- 43 + 72727 = 72770
- 97 + 72673 = 72770
- 109 + 72661 = 72770
- 127 + 72643 = 72770
Showing the first eight; more decompositions exist.
