Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527330, here are decompositions:
- 7 + 31527323 = 31527330
- 13 + 31527317 = 31527330
- 19 + 31527311 = 31527330
- 53 + 31527277 = 31527330
- 83 + 31527247 = 31527330
- 97 + 31527233 = 31527330
- 137 + 31527193 = 31527330
- 139 + 31527191 = 31527330
Showing the first eight; more decompositions exist.
