Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527822, here are decompositions:

5 + 31527817 = 31527822
41 + 31527781 = 31527822
113 + 31527709 = 31527822
163 + 31527659 = 31527822
239 + 31527583 = 31527822
281 + 31527541 = 31527822
331 + 31527491 = 31527822
409 + 31527413 = 31527822

Showing the first eight; more decompositions exist.
