Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530414, here are decompositions:

5 + 31530409 = 31530414
23 + 31530391 = 31530414
31 + 31530383 = 31530414
37 + 31530377 = 31530414
67 + 31530347 = 31530414
73 + 31530341 = 31530414
103 + 31530311 = 31530414
211 + 31530203 = 31530414

Showing the first eight; more decompositions exist.
