Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543302, here are decompositions:
- 29 + 31543273 = 31543302
- 59 + 31543243 = 31543302
- 71 + 31543231 = 31543302
- 79 + 31543223 = 31543302
- 83 + 31543219 = 31543302
- 139 + 31543163 = 31543302
- 199 + 31543103 = 31543302
- 223 + 31543079 = 31543302
Showing the first eight; more decompositions exist.
