Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534712, here are decompositions:

3 + 31534709 = 31534712
43 + 31534669 = 31534712
61 + 31534651 = 31534712
151 + 31534561 = 31534712
211 + 31534501 = 31534712
229 + 31534483 = 31534712
271 + 31534441 = 31534712
283 + 31534429 = 31534712

Showing the first eight; more decompositions exist.
