Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546042, here are decompositions:
- 23 + 31546019 = 31546042
- 29 + 31546013 = 31546042
- 83 + 31545959 = 31546042
- 89 + 31545953 = 31546042
- 293 + 31545749 = 31546042
- 401 + 31545641 = 31546042
- 419 + 31545623 = 31546042
- 431 + 31545611 = 31546042
Showing the first eight; more decompositions exist.
