Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530492, here are decompositions:

5 + 31530487 = 31530492
13 + 31530479 = 31530492
41 + 31530451 = 31530492
73 + 31530419 = 31530492
83 + 31530409 = 31530492
101 + 31530391 = 31530492
109 + 31530383 = 31530492
151 + 31530341 = 31530492

Showing the first eight; more decompositions exist.
