Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534514, here are decompositions:

13 + 31534501 = 31534514
31 + 31534483 = 31534514
73 + 31534441 = 31534514
103 + 31534411 = 31534514
181 + 31534333 = 31534514
283 + 31534231 = 31534514
331 + 31534183 = 31534514
373 + 31534141 = 31534514

Showing the first eight; more decompositions exist.
