Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563124, here are decompositions:

83 + 31563041 = 31563124
137 + 31562987 = 31563124
347 + 31562777 = 31563124
503 + 31562621 = 31563124
521 + 31562603 = 31563124
557 + 31562567 = 31563124
641 + 31562483 = 31563124
683 + 31562441 = 31563124

Showing the first eight; more decompositions exist.
