Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72798, here are decompositions:
- 31 + 72767 = 72798
- 59 + 72739 = 72798
- 71 + 72727 = 72798
- 79 + 72719 = 72798
- 97 + 72701 = 72798
- 109 + 72689 = 72798
- 127 + 72671 = 72798
- 137 + 72661 = 72798
Showing the first eight; more decompositions exist.
