Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534724, here are decompositions:

73 + 31534651 = 31534724
127 + 31534597 = 31534724
163 + 31534561 = 31534724
181 + 31534543 = 31534724
223 + 31534501 = 31534724
241 + 31534483 = 31534724
283 + 31534441 = 31534724
313 + 31534411 = 31534724

Showing the first eight; more decompositions exist.
