Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528066, here are decompositions:

29 + 31528037 = 31528066
47 + 31528019 = 31528066
179 + 31527887 = 31528066
239 + 31527827 = 31528066
389 + 31527677 = 31528066
569 + 31527497 = 31528066
653 + 31527413 = 31528066
659 + 31527407 = 31528066

Showing the first eight; more decompositions exist.
