Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503606, here are decompositions:

37 + 31503569 = 31503606
47 + 31503559 = 31503606
53 + 31503553 = 31503606
97 + 31503509 = 31503606
137 + 31503469 = 31503606
163 + 31503443 = 31503606
227 + 31503379 = 31503606
263 + 31503343 = 31503606

Showing the first eight; more decompositions exist.
