Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537670, here are decompositions:

61 + 31537609 = 31537670
67 + 31537603 = 31537670
79 + 31537591 = 31537670
97 + 31537573 = 31537670
127 + 31537543 = 31537670
163 + 31537507 = 31537670
193 + 31537477 = 31537670
331 + 31537339 = 31537670

Showing the first eight; more decompositions exist.
