Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534748, here are decompositions:
- 19 + 31534729 = 31534748
- 79 + 31534669 = 31534748
- 97 + 31534651 = 31534748
- 151 + 31534597 = 31534748
- 307 + 31534441 = 31534748
- 337 + 31534411 = 31534748
- 379 + 31534369 = 31534748
- 607 + 31534141 = 31534748
Showing the first eight; more decompositions exist.
