Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503446, here are decompositions:

3 + 31503443 = 31503446
67 + 31503379 = 31503446
103 + 31503343 = 31503446
109 + 31503337 = 31503446
229 + 31503217 = 31503446
307 + 31503139 = 31503446
487 + 31502959 = 31503446
523 + 31502923 = 31503446

Showing the first eight; more decompositions exist.
