Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576612, here are decompositions:

29 + 31576583 = 31576612
71 + 31576541 = 31576612
83 + 31576529 = 31576612
101 + 31576511 = 31576612
173 + 31576439 = 31576612
239 + 31576373 = 31576612
359 + 31576253 = 31576612
401 + 31576211 = 31576612

Showing the first eight; more decompositions exist.
