Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543232, here are decompositions:
- 13 + 31543219 = 31543232
- 163 + 31543069 = 31543232
- 223 + 31543009 = 31543232
- 241 + 31542991 = 31543232
- 283 + 31542949 = 31543232
- 421 + 31542811 = 31543232
- 433 + 31542799 = 31543232
- 601 + 31542631 = 31543232
Showing the first eight; more decompositions exist.
