Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600572, here are decompositions:

23 + 31600549 = 31600572
41 + 31600531 = 31600572
43 + 31600529 = 31600572
61 + 31600511 = 31600572
79 + 31600493 = 31600572
131 + 31600441 = 31600572
149 + 31600423 = 31600572
151 + 31600421 = 31600572

Showing the first eight; more decompositions exist.
