Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522854, here are decompositions:

7 + 31522847 = 31522854
31 + 31522823 = 31522854
107 + 31522747 = 31522854
137 + 31522717 = 31522854
191 + 31522663 = 31522854
197 + 31522657 = 31522854
241 + 31522613 = 31522854
257 + 31522597 = 31522854

Showing the first eight; more decompositions exist.
