Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484752, here are decompositions:

11 + 31484741 = 31484752
41 + 31484711 = 31484752
53 + 31484699 = 31484752
239 + 31484513 = 31484752
389 + 31484363 = 31484752
449 + 31484303 = 31484752
659 + 31484093 = 31484752
683 + 31484069 = 31484752

Showing the first eight; more decompositions exist.
