Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534770, here are decompositions:

13 + 31534757 = 31534770
17 + 31534753 = 31534770
19 + 31534751 = 31534770
31 + 31534739 = 31534770
41 + 31534729 = 31534770
61 + 31534709 = 31534770
79 + 31534691 = 31534770
101 + 31534669 = 31534770

Showing the first eight; more decompositions exist.
