Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522836, here are decompositions:

13 + 31522823 = 31522836
89 + 31522747 = 31522836
167 + 31522669 = 31522836
173 + 31522663 = 31522836
179 + 31522657 = 31522836
223 + 31522613 = 31522836
239 + 31522597 = 31522836
283 + 31522553 = 31522836

Showing the first eight; more decompositions exist.
