Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534658, here are decompositions:
- 7 + 31534651 = 31534658
- 61 + 31534597 = 31534658
- 97 + 31534561 = 31534658
- 157 + 31534501 = 31534658
- 229 + 31534429 = 31534658
- 541 + 31534117 = 31534658
- 601 + 31534057 = 31534658
- 607 + 31534051 = 31534658
Showing the first eight; more decompositions exist.
