Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503428, here are decompositions:

67 + 31503361 = 31503428
97 + 31503331 = 31503428
199 + 31503229 = 31503428
211 + 31503217 = 31503428
277 + 31503151 = 31503428
367 + 31503061 = 31503428
487 + 31502941 = 31503428
547 + 31502881 = 31503428

Showing the first eight; more decompositions exist.
