Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565526, here are decompositions:

29 + 31565497 = 31565526
53 + 31565473 = 31565526
89 + 31565437 = 31565526
103 + 31565423 = 31565526
127 + 31565399 = 31565526
149 + 31565377 = 31565526
173 + 31565353 = 31565526
227 + 31565299 = 31565526

Showing the first eight; more decompositions exist.
