Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456424, here are decompositions:

331 + 31456093 = 31456424
421 + 31456003 = 31456424
463 + 31455961 = 31456424
523 + 31455901 = 31456424
547 + 31455877 = 31456424
673 + 31455751 = 31456424
787 + 31455637 = 31456424
991 + 31455433 = 31456424

Showing the first eight; more decompositions exist.
