Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576088, here are decompositions:

79 + 31576009 = 31576088
97 + 31575991 = 31576088
151 + 31575937 = 31576088
211 + 31575877 = 31576088
421 + 31575667 = 31576088
601 + 31575487 = 31576088
619 + 31575469 = 31576088
727 + 31575361 = 31576088

Showing the first eight; more decompositions exist.
