Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534512, here are decompositions:

11 + 31534501 = 31534512
19 + 31534493 = 31534512
29 + 31534483 = 31534512
71 + 31534441 = 31534512
83 + 31534429 = 31534512
89 + 31534423 = 31534512
101 + 31534411 = 31534512
179 + 31534333 = 31534512

Showing the first eight; more decompositions exist.
