Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38130, here are decompositions:
- 11 + 38119 = 38130
- 17 + 38113 = 38130
- 47 + 38083 = 38130
- 61 + 38069 = 38130
- 83 + 38047 = 38130
- 137 + 37993 = 38130
- 139 + 37991 = 38130
- 163 + 37967 = 38130
Showing the first eight; more decompositions exist.
