Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456484, here are decompositions:

43 + 31456441 = 31456484
193 + 31456291 = 31456484
463 + 31456021 = 31456484
523 + 31455961 = 31456484
607 + 31455877 = 31456484
643 + 31455841 = 31456484
733 + 31455751 = 31456484
757 + 31455727 = 31456484

Showing the first eight; more decompositions exist.
