Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530410, here are decompositions:
- 19 + 31530391 = 31530410
- 61 + 31530349 = 31530410
- 199 + 31530211 = 31530410
- 229 + 31530181 = 31530410
- 313 + 31530097 = 31530410
- 349 + 31530061 = 31530410
- 367 + 31530043 = 31530410
- 409 + 31530001 = 31530410
Showing the first eight; more decompositions exist.
