Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 758, here are decompositions:
- 7 + 751 = 758
- 19 + 739 = 758
- 31 + 727 = 758
- 67 + 691 = 758
- 97 + 661 = 758
- 127 + 631 = 758
- 139 + 619 = 758
- 151 + 607 = 758
Showing the first eight; more decompositions exist.
