Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455926, here are decompositions:

37 + 31455889 = 31455926
67 + 31455859 = 31455926
97 + 31455829 = 31455926
199 + 31455727 = 31455926
223 + 31455703 = 31455926
277 + 31455649 = 31455926
499 + 31455427 = 31455926
613 + 31455313 = 31455926

Showing the first eight; more decompositions exist.
