Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503166, here are decompositions:

47 + 31503119 = 31503166
59 + 31503107 = 31503166
113 + 31503053 = 31503166
173 + 31502993 = 31503166
239 + 31502927 = 31503166
269 + 31502897 = 31503166
389 + 31502777 = 31503166
467 + 31502699 = 31503166

Showing the first eight; more decompositions exist.
