Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528466, here are decompositions:

7 + 31528459 = 31528466
19 + 31528447 = 31528466
103 + 31528363 = 31528466
139 + 31528327 = 31528466
199 + 31528267 = 31528466
373 + 31528093 = 31528466
397 + 31528069 = 31528466
499 + 31527967 = 31528466

Showing the first eight; more decompositions exist.
