Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567932, here are decompositions:

73 + 31567859 = 31567932
83 + 31567849 = 31567932
113 + 31567819 = 31567932
163 + 31567769 = 31567932
191 + 31567741 = 31567932
223 + 31567709 = 31567932
233 + 31567699 = 31567932
239 + 31567693 = 31567932

Showing the first eight; more decompositions exist.
