Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 764, here are decompositions:
- 3 + 761 = 764
- 7 + 757 = 764
- 13 + 751 = 764
- 31 + 733 = 764
- 37 + 727 = 764
- 73 + 691 = 764
- 103 + 661 = 764
- 151 + 613 = 764
Showing the first eight; more decompositions exist.
