Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534704, here are decompositions:

13 + 31534691 = 31534704
53 + 31534651 = 31534704
67 + 31534637 = 31534704
73 + 31534631 = 31534704
107 + 31534597 = 31534704
151 + 31534553 = 31534704
211 + 31534493 = 31534704
263 + 31534441 = 31534704

Showing the first eight; more decompositions exist.
