Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485304, here are decompositions:

3 + 31485301 = 31485304
83 + 31485221 = 31485304
107 + 31485197 = 31485304
113 + 31485191 = 31485304
197 + 31485107 = 31485304
281 + 31485023 = 31485304
311 + 31484993 = 31485304
401 + 31484903 = 31485304

Showing the first eight; more decompositions exist.
