Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577514, here are decompositions:

5 + 31577509 = 31577514
41 + 31577473 = 31577514
43 + 31577471 = 31577514
97 + 31577417 = 31577514
113 + 31577401 = 31577514
127 + 31577387 = 31577514
131 + 31577383 = 31577514
151 + 31577363 = 31577514

Showing the first eight; more decompositions exist.
