Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37128, here are decompositions:
- 5 + 37123 = 37128
- 11 + 37117 = 37128
- 31 + 37097 = 37128
- 41 + 37087 = 37128
- 67 + 37061 = 37128
- 71 + 37057 = 37128
- 79 + 37049 = 37128
- 89 + 37039 = 37128
Showing the first eight; more decompositions exist.
