Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526480, here are decompositions:
- 3 + 31526477 = 31526480
- 61 + 31526419 = 31526480
- 109 + 31526371 = 31526480
- 163 + 31526317 = 31526480
- 199 + 31526281 = 31526480
- 241 + 31526239 = 31526480
- 283 + 31526197 = 31526480
- 397 + 31526083 = 31526480
Showing the first eight; more decompositions exist.
