Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534636, here are decompositions:

5 + 31534631 = 31534636
47 + 31534589 = 31534636
83 + 31534553 = 31534636
149 + 31534487 = 31534636
179 + 31534457 = 31534636
293 + 31534343 = 31534636
389 + 31534247 = 31534636
449 + 31534187 = 31534636

Showing the first eight; more decompositions exist.
