Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519662, here are decompositions:

61 + 31519601 = 31519662
79 + 31519583 = 31519662
131 + 31519531 = 31519662
179 + 31519483 = 31519662
199 + 31519463 = 31519662
281 + 31519381 = 31519662
283 + 31519379 = 31519662
373 + 31519289 = 31519662

Showing the first eight; more decompositions exist.
