Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456214, here are decompositions:

193 + 31456021 = 31456214
211 + 31456003 = 31456214
313 + 31455901 = 31456214
337 + 31455877 = 31456214
373 + 31455841 = 31456214
463 + 31455751 = 31456214
487 + 31455727 = 31456214
577 + 31455637 = 31456214

Showing the first eight; more decompositions exist.
