Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72776, here are decompositions:
- 13 + 72763 = 72776
- 37 + 72739 = 72776
- 43 + 72733 = 72776
- 97 + 72679 = 72776
- 103 + 72673 = 72776
- 127 + 72649 = 72776
- 163 + 72613 = 72776
- 199 + 72577 = 72776
Showing the first eight; more decompositions exist.
