Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450482, here are decompositions:

31 + 31450451 = 31450482
53 + 31450429 = 31450482
59 + 31450423 = 31450482
61 + 31450421 = 31450482
71 + 31450411 = 31450482
73 + 31450409 = 31450482
113 + 31450369 = 31450482
131 + 31450351 = 31450482

Showing the first eight; more decompositions exist.
