Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527618, here are decompositions:
- 41 + 31527577 = 31527618
- 97 + 31527521 = 31527618
- 127 + 31527491 = 31527618
- 137 + 31527481 = 31527618
- 211 + 31527407 = 31527618
- 229 + 31527389 = 31527618
- 307 + 31527311 = 31527618
- 461 + 31527157 = 31527618
Showing the first eight; more decompositions exist.
