Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65790, here are decompositions:
- 13 + 65777 = 65790
- 29 + 65761 = 65790
- 59 + 65731 = 65790
- 61 + 65729 = 65790
- 71 + 65719 = 65790
- 73 + 65717 = 65790
- 83 + 65707 = 65790
- 89 + 65701 = 65790
Showing the first eight; more decompositions exist.
