Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589984, here are decompositions:

3 + 31589981 = 31589984
7 + 31589977 = 31589984
31 + 31589953 = 31589984
61 + 31589923 = 31589984
157 + 31589827 = 31589984
211 + 31589773 = 31589984
277 + 31589707 = 31589984
373 + 31589611 = 31589984

Showing the first eight; more decompositions exist.
