Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541652, here are decompositions:
- 19 + 31541633 = 31541652
- 41 + 31541611 = 31541652
- 61 + 31541591 = 31541652
- 71 + 31541581 = 31541652
- 83 + 31541569 = 31541652
- 89 + 31541563 = 31541652
- 223 + 31541429 = 31541652
- 251 + 31541401 = 31541652
Showing the first eight; more decompositions exist.
