Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530276, here are decompositions:
- 7 + 31530269 = 31530276
- 73 + 31530203 = 31530276
- 79 + 31530197 = 31530276
- 103 + 31530173 = 31530276
- 179 + 31530097 = 31530276
- 233 + 31530043 = 31530276
- 307 + 31529969 = 31530276
- 353 + 31529923 = 31530276
Showing the first eight; more decompositions exist.
