Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77832, here are decompositions:
- 19 + 77813 = 77832
- 31 + 77801 = 77832
- 59 + 77773 = 77832
- 71 + 77761 = 77832
- 89 + 77743 = 77832
- 101 + 77731 = 77832
- 109 + 77723 = 77832
- 113 + 77719 = 77832
Showing the first eight; more decompositions exist.
