Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447714, here are decompositions:

41 + 31447673 = 31447714
47 + 31447667 = 31447714
71 + 31447643 = 31447714
83 + 31447631 = 31447714
107 + 31447607 = 31447714
131 + 31447583 = 31447714
227 + 31447487 = 31447714
257 + 31447457 = 31447714

Showing the first eight; more decompositions exist.
