Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519482, here are decompositions:

19 + 31519463 = 31519482
23 + 31519459 = 31519482
41 + 31519441 = 31519482
79 + 31519403 = 31519482
101 + 31519381 = 31519482
103 + 31519379 = 31519482
193 + 31519289 = 31519482
229 + 31519253 = 31519482

Showing the first eight; more decompositions exist.
