Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457264, here are decompositions:

37 + 31457227 = 31457264
61 + 31457203 = 31457264
193 + 31457071 = 31457264
337 + 31456927 = 31457264
373 + 31456891 = 31457264
523 + 31456741 = 31457264
613 + 31456651 = 31457264
733 + 31456531 = 31457264

Showing the first eight; more decompositions exist.
