Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456964, here are decompositions:

37 + 31456927 = 31456964
61 + 31456903 = 31456964
73 + 31456891 = 31456964
223 + 31456741 = 31456964
313 + 31456651 = 31456964
367 + 31456597 = 31456964
433 + 31456531 = 31456964
463 + 31456501 = 31456964

Showing the first eight; more decompositions exist.
