Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546386, here are decompositions:
- 17 + 31546369 = 31546386
- 37 + 31546349 = 31546386
- 83 + 31546303 = 31546386
- 103 + 31546283 = 31546386
- 107 + 31546279 = 31546386
- 199 + 31546187 = 31546386
- 227 + 31546159 = 31546386
- 233 + 31546153 = 31546386
Showing the first eight; more decompositions exist.
