Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91770, here are decompositions:
- 13 + 91757 = 91770
- 17 + 91753 = 91770
- 37 + 91733 = 91770
- 59 + 91711 = 91770
- 67 + 91703 = 91770
- 79 + 91691 = 91770
- 97 + 91673 = 91770
- 131 + 91639 = 91770
Showing the first eight; more decompositions exist.
