Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528162, here are decompositions:

5 + 31528157 = 31528162
11 + 31528151 = 31528162
41 + 31528121 = 31528162
59 + 31528103 = 31528162
461 + 31527701 = 31528162
503 + 31527659 = 31528162
593 + 31527569 = 31528162
641 + 31527521 = 31528162

Showing the first eight; more decompositions exist.
