Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519762, here are decompositions:

59 + 31519703 = 31519762
83 + 31519679 = 31519762
89 + 31519673 = 31519762
101 + 31519661 = 31519762
179 + 31519583 = 31519762
191 + 31519571 = 31519762
359 + 31519403 = 31519762
383 + 31519379 = 31519762

Showing the first eight; more decompositions exist.
