Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527944, here are decompositions:

3 + 31527941 = 31527944
13 + 31527931 = 31527944
31 + 31527913 = 31527944
127 + 31527817 = 31527944
157 + 31527787 = 31527944
163 + 31527781 = 31527944
241 + 31527703 = 31527944
367 + 31527577 = 31527944

Showing the first eight; more decompositions exist.
