Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527806, here are decompositions:

19 + 31527787 = 31527806
97 + 31527709 = 31527806
103 + 31527703 = 31527806
109 + 31527697 = 31527806
223 + 31527583 = 31527806
229 + 31527577 = 31527806
283 + 31527523 = 31527806
307 + 31527499 = 31527806

Showing the first eight; more decompositions exist.
