Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484984, here are decompositions:

43 + 31484941 = 31484984
73 + 31484911 = 31484984
163 + 31484821 = 31484984
337 + 31484647 = 31484984
367 + 31484617 = 31484984
523 + 31484461 = 31484984
571 + 31484413 = 31484984
607 + 31484377 = 31484984

Showing the first eight; more decompositions exist.
