Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542082, here are decompositions:
- 59 + 31542023 = 31542082
- 71 + 31542011 = 31542082
- 101 + 31541981 = 31542082
- 149 + 31541933 = 31542082
- 179 + 31541903 = 31542082
- 191 + 31541891 = 31542082
- 389 + 31541693 = 31542082
- 431 + 31541651 = 31542082
Showing the first eight; more decompositions exist.
