Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607382, here are decompositions:

19 + 31607363 = 31607382
41 + 31607341 = 31607382
73 + 31607309 = 31607382
83 + 31607299 = 31607382
89 + 31607293 = 31607382
101 + 31607281 = 31607382
181 + 31607201 = 31607382
229 + 31607153 = 31607382

Showing the first eight; more decompositions exist.
