Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538714, here are decompositions:

3 + 31538711 = 31538714
43 + 31538671 = 31538714
61 + 31538653 = 31538714
73 + 31538641 = 31538714
157 + 31538557 = 31538714
211 + 31538503 = 31538714
223 + 31538491 = 31538714
241 + 31538473 = 31538714

Showing the first eight; more decompositions exist.
