Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474882, here are decompositions:

53 + 31474829 = 31474882
149 + 31474733 = 31474882
191 + 31474691 = 31474882
281 + 31474601 = 31474882
311 + 31474571 = 31474882
401 + 31474481 = 31474882
449 + 31474433 = 31474882
479 + 31474403 = 31474882

Showing the first eight; more decompositions exist.
