Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567506, here are decompositions:

79 + 31567427 = 31567506
109 + 31567397 = 31567506
137 + 31567369 = 31567506
193 + 31567313 = 31567506
227 + 31567279 = 31567506
239 + 31567267 = 31567506
293 + 31567213 = 31567506
349 + 31567157 = 31567506

Showing the first eight; more decompositions exist.
