Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543226, here are decompositions:
- 3 + 31543223 = 31543226
- 7 + 31543219 = 31543226
- 19 + 31543207 = 31543226
- 157 + 31543069 = 31543226
- 277 + 31542949 = 31543226
- 283 + 31542943 = 31543226
- 349 + 31542877 = 31543226
- 397 + 31542829 = 31543226
Showing the first eight; more decompositions exist.
