Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534688, here are decompositions:
- 19 + 31534669 = 31534688
- 37 + 31534651 = 31534688
- 127 + 31534561 = 31534688
- 277 + 31534411 = 31534688
- 457 + 31534231 = 31534688
- 547 + 31534141 = 31534688
- 571 + 31534117 = 31534688
- 631 + 31534057 = 31534688
Showing the first eight; more decompositions exist.
