Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588794, here are decompositions:

101 + 31588693 = 31588794
137 + 31588657 = 31588794
151 + 31588643 = 31588794
163 + 31588631 = 31588794
191 + 31588603 = 31588794
233 + 31588561 = 31588794
271 + 31588523 = 31588794
311 + 31588483 = 31588794

Showing the first eight; more decompositions exist.
