Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457036, here are decompositions:

109 + 31456927 = 31457036
367 + 31456669 = 31457036
397 + 31456639 = 31457036
439 + 31456597 = 31457036
607 + 31456429 = 31457036
757 + 31456279 = 31457036
937 + 31456099 = 31457036
1033 + 31456003 = 31457036

Showing the first eight; more decompositions exist.
