Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530498, here are decompositions:

11 + 31530487 = 31530498
19 + 31530479 = 31530498
47 + 31530451 = 31530498
61 + 31530437 = 31530498
79 + 31530419 = 31530498
89 + 31530409 = 31530498
107 + 31530391 = 31530498
149 + 31530349 = 31530498

Showing the first eight; more decompositions exist.
