Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444762, here are decompositions:

3 + 31444759 = 31444762
71 + 31444691 = 31444762
101 + 31444661 = 31444762
113 + 31444649 = 31444762
131 + 31444631 = 31444762
359 + 31444403 = 31444762
383 + 31444379 = 31444762
449 + 31444313 = 31444762

Showing the first eight; more decompositions exist.
