Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516758, here are decompositions:

5 + 31516753 = 31516758
29 + 31516729 = 31516758
59 + 31516699 = 31516758
61 + 31516697 = 31516758
89 + 31516669 = 31516758
127 + 31516631 = 31516758
131 + 31516627 = 31516758
139 + 31516619 = 31516758

Showing the first eight; more decompositions exist.
