Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576714, here are decompositions:

5 + 31576709 = 31576714
11 + 31576703 = 31576714
41 + 31576673 = 31576714
131 + 31576583 = 31576714
173 + 31576541 = 31576714
311 + 31576403 = 31576714
347 + 31576367 = 31576714
431 + 31576283 = 31576714

Showing the first eight; more decompositions exist.
