Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567908, here are decompositions:

59 + 31567849 = 31567908
89 + 31567819 = 31567908
139 + 31567769 = 31567908
167 + 31567741 = 31567908
179 + 31567729 = 31567908
191 + 31567717 = 31567908
199 + 31567709 = 31567908
227 + 31567681 = 31567908

Showing the first eight; more decompositions exist.
