Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544528, here are decompositions:

19 + 31544509 = 31544528
157 + 31544371 = 31544528
181 + 31544347 = 31544528
307 + 31544221 = 31544528
349 + 31544179 = 31544528
397 + 31544131 = 31544528
439 + 31544089 = 31544528
487 + 31544041 = 31544528

Showing the first eight; more decompositions exist.
