Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553622, here are decompositions:

5 + 31553617 = 31553622
13 + 31553609 = 31553622
103 + 31553519 = 31553622
239 + 31553383 = 31553622
263 + 31553359 = 31553622
271 + 31553351 = 31553622
283 + 31553339 = 31553622
349 + 31553273 = 31553622

Showing the first eight; more decompositions exist.
