Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503994, here are decompositions:

17 + 31503977 = 31503994
23 + 31503971 = 31503994
83 + 31503911 = 31503994
107 + 31503887 = 31503994
131 + 31503863 = 31503994
281 + 31503713 = 31503994
653 + 31503341 = 31503994
827 + 31503167 = 31503994

Showing the first eight; more decompositions exist.
