Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72788, here are decompositions:
- 61 + 72727 = 72788
- 109 + 72679 = 72788
- 127 + 72661 = 72788
- 139 + 72649 = 72788
- 211 + 72577 = 72788
- 229 + 72559 = 72788
- 241 + 72547 = 72788
- 307 + 72481 = 72788
Showing the first eight; more decompositions exist.
