Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456036, here are decompositions:

23 + 31456013 = 31456036
89 + 31455947 = 31456036
107 + 31455929 = 31456036
167 + 31455869 = 31456036
233 + 31455803 = 31456036
389 + 31455647 = 31456036
503 + 31455533 = 31456036
587 + 31455449 = 31456036

Showing the first eight; more decompositions exist.
