Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576734, here are decompositions:

31 + 31576703 = 31576734
53 + 31576681 = 31576734
61 + 31576673 = 31576734
151 + 31576583 = 31576734
193 + 31576541 = 31576734
223 + 31576511 = 31576734
251 + 31576483 = 31576734
257 + 31576477 = 31576734

Showing the first eight; more decompositions exist.
