Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576692, here are decompositions:

11 + 31576681 = 31576692
19 + 31576673 = 31576692
53 + 31576639 = 31576692
73 + 31576619 = 31576692
109 + 31576583 = 31576692
113 + 31576579 = 31576692
151 + 31576541 = 31576692
163 + 31576529 = 31576692

Showing the first eight; more decompositions exist.
