Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456044, here are decompositions:

23 + 31456021 = 31456044
31 + 31456013 = 31456044
41 + 31456003 = 31456044
83 + 31455961 = 31456044
97 + 31455947 = 31456044
167 + 31455877 = 31456044
223 + 31455821 = 31456044
241 + 31455803 = 31456044

Showing the first eight; more decompositions exist.
