Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516444, here are decompositions:
- 17 + 31516427 = 31516444
- 83 + 31516361 = 31516444
- 191 + 31516253 = 31516444
- 383 + 31516061 = 31516444
- 503 + 31515941 = 31516444
- 563 + 31515881 = 31516444
- 587 + 31515857 = 31516444
- 677 + 31515767 = 31516444
Showing the first eight; more decompositions exist.
