Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501850, here are decompositions:

19 + 31501831 = 31501850
31 + 31501819 = 31501850
43 + 31501807 = 31501850
109 + 31501741 = 31501850
151 + 31501699 = 31501850
181 + 31501669 = 31501850
229 + 31501621 = 31501850
283 + 31501567 = 31501850

Showing the first eight; more decompositions exist.
