Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534764, here are decompositions:

7 + 31534757 = 31534764
11 + 31534753 = 31534764
13 + 31534751 = 31534764
73 + 31534691 = 31534764
113 + 31534651 = 31534764
127 + 31534637 = 31534764
167 + 31534597 = 31534764
211 + 31534553 = 31534764

Showing the first eight; more decompositions exist.
