Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534412, here are decompositions:
- 43 + 31534369 = 31534412
- 79 + 31534333 = 31534412
- 181 + 31534231 = 31534412
- 229 + 31534183 = 31534412
- 271 + 31534141 = 31534412
- 379 + 31534033 = 31534412
- 433 + 31533979 = 31534412
- 463 + 31533949 = 31534412
Showing the first eight; more decompositions exist.
