Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534664, here are decompositions:

13 + 31534651 = 31534664
67 + 31534597 = 31534664
103 + 31534561 = 31534664
163 + 31534501 = 31534664
181 + 31534483 = 31534664
223 + 31534441 = 31534664
241 + 31534423 = 31534664
331 + 31534333 = 31534664

Showing the first eight; more decompositions exist.
