Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503684, here are decompositions:

11 + 31503673 = 31503684
41 + 31503643 = 31503684
53 + 31503631 = 31503684
127 + 31503557 = 31503684
131 + 31503553 = 31503684
241 + 31503443 = 31503684
347 + 31503337 = 31503684
353 + 31503331 = 31503684

Showing the first eight; more decompositions exist.
