Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537634, here are decompositions:

3 + 31537631 = 31537634
31 + 31537603 = 31537634
43 + 31537591 = 31537634
61 + 31537573 = 31537634
127 + 31537507 = 31537634
157 + 31537477 = 31537634
307 + 31537327 = 31537634
367 + 31537267 = 31537634

Showing the first eight; more decompositions exist.
