Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522884, here are decompositions:

11 + 31522873 = 31522884
37 + 31522847 = 31522884
61 + 31522823 = 31522884
137 + 31522747 = 31522884
167 + 31522717 = 31522884
191 + 31522693 = 31522884
227 + 31522657 = 31522884
251 + 31522633 = 31522884

Showing the first eight; more decompositions exist.
