Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567592, here are decompositions:

79 + 31567513 = 31567592
163 + 31567429 = 31567592
181 + 31567411 = 31567592
223 + 31567369 = 31567592
313 + 31567279 = 31567592
373 + 31567219 = 31567592
379 + 31567213 = 31567592
439 + 31567153 = 31567592

Showing the first eight; more decompositions exist.
