Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517222, here are decompositions:
- 73 + 31517149 = 31517222
- 211 + 31517011 = 31517222
- 229 + 31516993 = 31517222
- 241 + 31516981 = 31517222
- 271 + 31516951 = 31517222
- 433 + 31516789 = 31517222
- 523 + 31516699 = 31517222
- 619 + 31516603 = 31517222
Showing the first eight; more decompositions exist.
