Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514462, here are decompositions:

13 + 31514449 = 31514462
43 + 31514419 = 31514462
61 + 31514401 = 31514462
223 + 31514239 = 31514462
241 + 31514221 = 31514462
271 + 31514191 = 31514462
313 + 31514149 = 31514462
349 + 31514113 = 31514462

Showing the first eight; more decompositions exist.
