Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522794, here are decompositions:

47 + 31522747 = 31522794
101 + 31522693 = 31522794
131 + 31522663 = 31522794
137 + 31522657 = 31522794
181 + 31522613 = 31522794
197 + 31522597 = 31522794
211 + 31522583 = 31522794
241 + 31522553 = 31522794

Showing the first eight; more decompositions exist.
