Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528214, here are decompositions:

7 + 31528207 = 31528214
43 + 31528171 = 31528214
103 + 31528111 = 31528214
283 + 31527931 = 31528214
397 + 31527817 = 31528214
433 + 31527781 = 31528214
631 + 31527583 = 31528214
673 + 31527541 = 31528214

Showing the first eight; more decompositions exist.
