Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506314, here are decompositions:

3 + 31506311 = 31506314
31 + 31506283 = 31506314
43 + 31506271 = 31506314
67 + 31506247 = 31506314
211 + 31506103 = 31506314
223 + 31506091 = 31506314
283 + 31506031 = 31506314
331 + 31505983 = 31506314

Showing the first eight; more decompositions exist.
