Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530422, here are decompositions:

3 + 31530419 = 31530422
13 + 31530409 = 31530422
31 + 31530391 = 31530422
73 + 31530349 = 31530422
211 + 31530211 = 31530422
241 + 31530181 = 31530422
379 + 31530043 = 31530422
421 + 31530001 = 31530422

Showing the first eight; more decompositions exist.
