Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455714, here are decompositions:

11 + 31455703 = 31455714
13 + 31455701 = 31455714
67 + 31455647 = 31455714
83 + 31455631 = 31455714
181 + 31455533 = 31455714
193 + 31455521 = 31455714
211 + 31455503 = 31455714
281 + 31455433 = 31455714

Showing the first eight; more decompositions exist.
