Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482988, here are decompositions:

11 + 31482977 = 31482988
41 + 31482947 = 31482988
149 + 31482839 = 31482988
167 + 31482821 = 31482988
227 + 31482761 = 31482988
281 + 31482707 = 31482988
347 + 31482641 = 31482988
389 + 31482599 = 31482988

Showing the first eight; more decompositions exist.
