Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546138, here are decompositions:
- 131 + 31546007 = 31546138
- 179 + 31545959 = 31546138
- 251 + 31545887 = 31546138
- 389 + 31545749 = 31546138
- 401 + 31545737 = 31546138
- 509 + 31545629 = 31546138
- 809 + 31545329 = 31546138
- 821 + 31545317 = 31546138
Showing the first eight; more decompositions exist.
