Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477634, here are decompositions:
- 31 + 31477603 = 31477634
- 73 + 31477561 = 31477634
- 127 + 31477507 = 31477634
- 151 + 31477483 = 31477634
- 211 + 31477423 = 31477634
- 283 + 31477351 = 31477634
- 313 + 31477321 = 31477634
- 421 + 31477213 = 31477634
Showing the first eight; more decompositions exist.
