Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543246, here are decompositions:
- 3 + 31543243 = 31543246
- 23 + 31543223 = 31543246
- 29 + 31543217 = 31543246
- 83 + 31543163 = 31543246
- 113 + 31543133 = 31543246
- 167 + 31543079 = 31543246
- 179 + 31543067 = 31543246
- 227 + 31543019 = 31543246
Showing the first eight; more decompositions exist.
