Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526340, here are decompositions:
- 23 + 31526317 = 31526340
- 59 + 31526281 = 31526340
- 67 + 31526273 = 31526340
- 101 + 31526239 = 31526340
- 113 + 31526227 = 31526340
- 127 + 31526213 = 31526340
- 149 + 31526191 = 31526340
- 151 + 31526189 = 31526340
Showing the first eight; more decompositions exist.
