Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525566, here are decompositions:
- 13 + 31525553 = 31525566
- 29 + 31525537 = 31525566
- 67 + 31525499 = 31525566
- 89 + 31525477 = 31525566
- 199 + 31525367 = 31525566
- 223 + 31525343 = 31525566
- 277 + 31525289 = 31525566
- 283 + 31525283 = 31525566
Showing the first eight; more decompositions exist.
