Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503612, here are decompositions:

43 + 31503569 = 31503612
53 + 31503559 = 31503612
59 + 31503553 = 31503612
83 + 31503529 = 31503612
103 + 31503509 = 31503612
233 + 31503379 = 31503612
251 + 31503361 = 31503612
269 + 31503343 = 31503612

Showing the first eight; more decompositions exist.
