Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530622, here are decompositions:

5 + 31530617 = 31530622
29 + 31530593 = 31530622
239 + 31530383 = 31530622
281 + 31530341 = 31530622
311 + 31530311 = 31530622
353 + 31530269 = 31530622
419 + 31530203 = 31530622
449 + 31530173 = 31530622

Showing the first eight; more decompositions exist.
