Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534572, here are decompositions:

11 + 31534561 = 31534572
19 + 31534553 = 31534572
29 + 31534543 = 31534572
71 + 31534501 = 31534572
79 + 31534493 = 31534572
89 + 31534483 = 31534572
131 + 31534441 = 31534572
149 + 31534423 = 31534572

Showing the first eight; more decompositions exist.
