Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571704, here are decompositions:

5 + 31571699 = 31571704
53 + 31571651 = 31571704
83 + 31571621 = 31571704
113 + 31571591 = 31571704
251 + 31571453 = 31571704
257 + 31571447 = 31571704
401 + 31571303 = 31571704
491 + 31571213 = 31571704

Showing the first eight; more decompositions exist.
