Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567852, here are decompositions:

3 + 31567849 = 31567852
83 + 31567769 = 31567852
179 + 31567673 = 31567852
233 + 31567619 = 31567852
293 + 31567559 = 31567852
401 + 31567451 = 31567852
761 + 31567091 = 31567852
809 + 31567043 = 31567852

Showing the first eight; more decompositions exist.
