Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503946, here are decompositions:

17 + 31503929 = 31503946
29 + 31503917 = 31503946
59 + 31503887 = 31503946
83 + 31503863 = 31503946
137 + 31503809 = 31503946
167 + 31503779 = 31503946
197 + 31503749 = 31503946
233 + 31503713 = 31503946

Showing the first eight; more decompositions exist.
