Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507932, here are decompositions:

11 + 31507921 = 31507932
19 + 31507913 = 31507932
31 + 31507901 = 31507932
109 + 31507823 = 31507932
139 + 31507793 = 31507932
179 + 31507753 = 31507932
193 + 31507739 = 31507932
223 + 31507709 = 31507932

Showing the first eight; more decompositions exist.
