Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534610, here are decompositions:
- 13 + 31534597 = 31534610
- 67 + 31534543 = 31534610
- 109 + 31534501 = 31534610
- 127 + 31534483 = 31534610
- 181 + 31534429 = 31534610
- 199 + 31534411 = 31534610
- 241 + 31534369 = 31534610
- 277 + 31534333 = 31534610
Showing the first eight; more decompositions exist.
