Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538652, here are decompositions:
- 11 + 31538641 = 31538652
- 23 + 31538629 = 31538652
- 29 + 31538623 = 31538652
- 71 + 31538581 = 31538652
- 73 + 31538579 = 31538652
- 83 + 31538569 = 31538652
- 113 + 31538539 = 31538652
- 149 + 31538503 = 31538652
Showing the first eight; more decompositions exist.
