Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541692, here are decompositions:
- 41 + 31541651 = 31541692
- 59 + 31541633 = 31541692
- 101 + 31541591 = 31541692
- 263 + 31541429 = 31541692
- 293 + 31541399 = 31541692
- 449 + 31541243 = 31541692
- 563 + 31541129 = 31541692
- 641 + 31541051 = 31541692
Showing the first eight; more decompositions exist.
