Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546190, here are decompositions:
- 3 + 31546187 = 31546190
- 31 + 31546159 = 31546190
- 37 + 31546153 = 31546190
- 61 + 31546129 = 31546190
- 79 + 31546111 = 31546190
- 127 + 31546063 = 31546190
- 199 + 31545991 = 31546190
- 271 + 31545919 = 31546190
Showing the first eight; more decompositions exist.
