Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527336, here are decompositions:
- 13 + 31527323 = 31527336
- 19 + 31527317 = 31527336
- 59 + 31527277 = 31527336
- 83 + 31527253 = 31527336
- 89 + 31527247 = 31527336
- 103 + 31527233 = 31527336
- 163 + 31527173 = 31527336
- 179 + 31527157 = 31527336
Showing the first eight; more decompositions exist.
