Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546018, here are decompositions:
- 5 + 31546013 = 31546018
- 11 + 31546007 = 31546018
- 59 + 31545959 = 31546018
- 131 + 31545887 = 31546018
- 269 + 31545749 = 31546018
- 281 + 31545737 = 31546018
- 389 + 31545629 = 31546018
- 419 + 31545599 = 31546018
Showing the first eight; more decompositions exist.
