Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530522, here are decompositions:

43 + 31530479 = 31530522
71 + 31530451 = 31530522
103 + 31530419 = 31530522
113 + 31530409 = 31530522
131 + 31530391 = 31530522
139 + 31530383 = 31530522
173 + 31530349 = 31530522
181 + 31530341 = 31530522

Showing the first eight; more decompositions exist.
