Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532670, here are decompositions:

11 + 31532659 = 31532670
17 + 31532653 = 31532670
31 + 31532639 = 31532670
73 + 31532597 = 31532670
83 + 31532587 = 31532670
89 + 31532581 = 31532670
97 + 31532573 = 31532670
131 + 31532539 = 31532670

Showing the first eight; more decompositions exist.
