Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501852, here are decompositions:

3 + 31501849 = 31501852
29 + 31501823 = 31501852
71 + 31501781 = 31501852
101 + 31501751 = 31501852
131 + 31501721 = 31501852
191 + 31501661 = 31501852
233 + 31501619 = 31501852
269 + 31501583 = 31501852

Showing the first eight; more decompositions exist.
