Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486524, here are decompositions:

31 + 31486493 = 31486524
61 + 31486463 = 31486524
67 + 31486457 = 31486524
71 + 31486453 = 31486524
73 + 31486451 = 31486524
101 + 31486423 = 31486524
107 + 31486417 = 31486524
131 + 31486393 = 31486524

Showing the first eight; more decompositions exist.
