Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528280, here are decompositions:
- 13 + 31528267 = 31528280
- 67 + 31528213 = 31528280
- 73 + 31528207 = 31528280
- 109 + 31528171 = 31528280
- 211 + 31528069 = 31528280
- 283 + 31527997 = 31528280
- 313 + 31527967 = 31528280
- 349 + 31527931 = 31528280
Showing the first eight; more decompositions exist.
