Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565924, here are decompositions:

7 + 31565917 = 31565924
37 + 31565887 = 31565924
73 + 31565851 = 31565924
163 + 31565761 = 31565924
211 + 31565713 = 31565924
223 + 31565701 = 31565924
433 + 31565491 = 31565924
463 + 31565461 = 31565924

Showing the first eight; more decompositions exist.
