Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503624, here are decompositions:

67 + 31503557 = 31503624
71 + 31503553 = 31503624
181 + 31503443 = 31503624
263 + 31503361 = 31503624
281 + 31503343 = 31503624
283 + 31503341 = 31503624
293 + 31503331 = 31503624
311 + 31503313 = 31503624

Showing the first eight; more decompositions exist.
