Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528622, here are decompositions:

43 + 31528579 = 31528622
163 + 31528459 = 31528622
331 + 31528291 = 31528622
409 + 31528213 = 31528622
691 + 31527931 = 31528622
709 + 31527913 = 31528622
919 + 31527703 = 31528622
1039 + 31527583 = 31528622

Showing the first eight; more decompositions exist.
