Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527308, here are decompositions:
- 31 + 31527277 = 31527308
- 61 + 31527247 = 31527308
- 97 + 31527211 = 31527308
- 151 + 31527157 = 31527308
- 157 + 31527151 = 31527308
- 199 + 31527109 = 31527308
- 367 + 31526941 = 31527308
- 409 + 31526899 = 31527308
Showing the first eight; more decompositions exist.
