Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517702, here are decompositions:

3 + 31517699 = 31517702
61 + 31517641 = 31517702
211 + 31517491 = 31517702
313 + 31517389 = 31517702
691 + 31517011 = 31517702
709 + 31516993 = 31517702
751 + 31516951 = 31517702
823 + 31516879 = 31517702

Showing the first eight; more decompositions exist.
