Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503922, here are decompositions:

5 + 31503917 = 31503922
11 + 31503911 = 31503922
59 + 31503863 = 31503922
113 + 31503809 = 31503922
173 + 31503749 = 31503922
353 + 31503569 = 31503922
479 + 31503443 = 31503922
599 + 31503323 = 31503922

Showing the first eight; more decompositions exist.
