Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567550, here are decompositions:

37 + 31567513 = 31567550
139 + 31567411 = 31567550
181 + 31567369 = 31567550
271 + 31567279 = 31567550
283 + 31567267 = 31567550
331 + 31567219 = 31567550
337 + 31567213 = 31567550
397 + 31567153 = 31567550

Showing the first eight; more decompositions exist.
