Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72792, here are decompositions:
- 29 + 72763 = 72792
- 53 + 72739 = 72792
- 59 + 72733 = 72792
- 73 + 72719 = 72792
- 103 + 72689 = 72792
- 113 + 72679 = 72792
- 131 + 72661 = 72792
- 149 + 72643 = 72792
Showing the first eight; more decompositions exist.
