Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456004, here are decompositions:

43 + 31455961 = 31456004
103 + 31455901 = 31456004
127 + 31455877 = 31456004
163 + 31455841 = 31456004
277 + 31455727 = 31456004
367 + 31455637 = 31456004
373 + 31455631 = 31456004
571 + 31455433 = 31456004

Showing the first eight; more decompositions exist.
