Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534628, here are decompositions:

31 + 31534597 = 31534628
67 + 31534561 = 31534628
127 + 31534501 = 31534628
199 + 31534429 = 31534628
331 + 31534297 = 31534628
397 + 31534231 = 31534628
487 + 31534141 = 31534628
571 + 31534057 = 31534628

Showing the first eight; more decompositions exist.
