Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559732, here are decompositions:

13 + 31559719 = 31559732
73 + 31559659 = 31559732
79 + 31559653 = 31559732
109 + 31559623 = 31559732
331 + 31559401 = 31559732
349 + 31559383 = 31559732
571 + 31559161 = 31559732
601 + 31559131 = 31559732

Showing the first eight; more decompositions exist.
