Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446922, here are decompositions:

5 + 31446917 = 31446922
29 + 31446893 = 31446922
83 + 31446839 = 31446922
173 + 31446749 = 31446922
179 + 31446743 = 31446922
233 + 31446689 = 31446922
281 + 31446641 = 31446922
359 + 31446563 = 31446922

Showing the first eight; more decompositions exist.
