Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528646, here are decompositions:

13 + 31528633 = 31528646
67 + 31528579 = 31528646
73 + 31528573 = 31528646
199 + 31528447 = 31528646
283 + 31528363 = 31528646
367 + 31528279 = 31528646
379 + 31528267 = 31528646
433 + 31528213 = 31528646

Showing the first eight; more decompositions exist.
