Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503404, here are decompositions:

43 + 31503361 = 31503404
61 + 31503343 = 31503404
67 + 31503337 = 31503404
73 + 31503331 = 31503404
223 + 31503181 = 31503404
463 + 31502941 = 31503404
523 + 31502881 = 31503404
547 + 31502857 = 31503404

Showing the first eight; more decompositions exist.
