Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516678, here are decompositions:
- 47 + 31516631 = 31516678
- 59 + 31516619 = 31516678
- 107 + 31516571 = 31516678
- 251 + 31516427 = 31516678
- 317 + 31516361 = 31516678
- 359 + 31516319 = 31516678
- 521 + 31516157 = 31516678
- 569 + 31516109 = 31516678
Showing the first eight; more decompositions exist.
