Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477548, here are decompositions:
- 5 + 31477543 = 31477548
- 41 + 31477507 = 31477548
- 101 + 31477447 = 31477548
- 149 + 31477399 = 31477548
- 197 + 31477351 = 31477548
- 199 + 31477349 = 31477548
- 227 + 31477321 = 31477548
- 257 + 31477291 = 31477548
Showing the first eight; more decompositions exist.
