Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39790, here are decompositions:
- 11 + 39779 = 39790
- 29 + 39761 = 39790
- 41 + 39749 = 39790
- 71 + 39719 = 39790
- 131 + 39659 = 39790
- 167 + 39623 = 39790
- 227 + 39563 = 39790
- 239 + 39551 = 39790
Showing the first eight; more decompositions exist.
