Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534942, here are decompositions:

29 + 31534913 = 31534942
71 + 31534871 = 31534942
191 + 31534751 = 31534942
233 + 31534709 = 31534942
251 + 31534691 = 31534942
311 + 31534631 = 31534942
353 + 31534589 = 31534942
389 + 31534553 = 31534942

Showing the first eight; more decompositions exist.
