Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480044, here are decompositions:

23 + 31480021 = 31480044
83 + 31479961 = 31480044
97 + 31479947 = 31480044
163 + 31479881 = 31480044
223 + 31479821 = 31480044
227 + 31479817 = 31480044
241 + 31479803 = 31480044
251 + 31479793 = 31480044

Showing the first eight; more decompositions exist.
