Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456046, here are decompositions:

43 + 31456003 = 31456046
157 + 31455889 = 31456046
397 + 31455649 = 31456046
409 + 31455637 = 31456046
547 + 31455499 = 31456046
613 + 31455433 = 31456046
619 + 31455427 = 31456046
733 + 31455313 = 31456046

Showing the first eight; more decompositions exist.
