Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517024, here are decompositions:

3 + 31517021 = 31517024
13 + 31517011 = 31517024
31 + 31516993 = 31517024
43 + 31516981 = 31517024
73 + 31516951 = 31517024
271 + 31516753 = 31517024
397 + 31516627 = 31517024
421 + 31516603 = 31517024

Showing the first eight; more decompositions exist.
