Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72786, here are decompositions:
- 19 + 72767 = 72786
- 23 + 72763 = 72786
- 47 + 72739 = 72786
- 53 + 72733 = 72786
- 59 + 72727 = 72786
- 67 + 72719 = 72786
- 79 + 72707 = 72786
- 97 + 72689 = 72786
Showing the first eight; more decompositions exist.
