Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576722, here are decompositions:

13 + 31576709 = 31576722
19 + 31576703 = 31576722
41 + 31576681 = 31576722
83 + 31576639 = 31576722
103 + 31576619 = 31576722
139 + 31576583 = 31576722
173 + 31576549 = 31576722
181 + 31576541 = 31576722

Showing the first eight; more decompositions exist.
