Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522566, here are decompositions:

13 + 31522553 = 31522566
17 + 31522549 = 31522566
37 + 31522529 = 31522566
43 + 31522523 = 31522566
73 + 31522493 = 31522566
107 + 31522459 = 31522566
193 + 31522373 = 31522566
227 + 31522339 = 31522566

Showing the first eight; more decompositions exist.
