Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528382, here are decompositions:

19 + 31528363 = 31528382
103 + 31528279 = 31528382
211 + 31528171 = 31528382
271 + 31528111 = 31528382
313 + 31528069 = 31528382
601 + 31527781 = 31528382
673 + 31527709 = 31528382
859 + 31527523 = 31528382

Showing the first eight; more decompositions exist.
