Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534678, here are decompositions:

41 + 31534637 = 31534678
47 + 31534631 = 31534678
89 + 31534589 = 31534678
191 + 31534487 = 31534678
251 + 31534427 = 31534678
431 + 31534247 = 31534678
479 + 31534199 = 31534678
491 + 31534187 = 31534678

Showing the first eight; more decompositions exist.
