Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483664, here are decompositions:

67 + 31483597 = 31483664
193 + 31483471 = 31483664
211 + 31483453 = 31483664
313 + 31483351 = 31483664
337 + 31483327 = 31483664
547 + 31483117 = 31483664
571 + 31483093 = 31483664
577 + 31483087 = 31483664

Showing the first eight; more decompositions exist.
