Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532552, here are decompositions:
- 13 + 31532539 = 31532552
- 31 + 31532521 = 31532552
- 151 + 31532401 = 31532552
- 199 + 31532353 = 31532552
- 211 + 31532341 = 31532552
- 223 + 31532329 = 31532552
- 229 + 31532323 = 31532552
- 283 + 31532269 = 31532552
Showing the first eight; more decompositions exist.
