Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527314, here are decompositions:
- 3 + 31527311 = 31527314
- 37 + 31527277 = 31527314
- 61 + 31527253 = 31527314
- 67 + 31527247 = 31527314
- 103 + 31527211 = 31527314
- 157 + 31527157 = 31527314
- 163 + 31527151 = 31527314
- 373 + 31526941 = 31527314
Showing the first eight; more decompositions exist.
