Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541694, here are decompositions:
- 17 + 31541677 = 31541694
- 43 + 31541651 = 31541694
- 61 + 31541633 = 31541694
- 83 + 31541611 = 31541694
- 97 + 31541597 = 31541694
- 103 + 31541591 = 31541694
- 113 + 31541581 = 31541694
- 131 + 31541563 = 31541694
Showing the first eight; more decompositions exist.
