Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500892, here are decompositions:

29 + 31500863 = 31500892
83 + 31500809 = 31500892
173 + 31500719 = 31500892
179 + 31500713 = 31500892
191 + 31500701 = 31500892
233 + 31500659 = 31500892
281 + 31500611 = 31500892
383 + 31500509 = 31500892

Showing the first eight; more decompositions exist.
