Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590036, here are decompositions:

29 + 31590007 = 31590036
53 + 31589983 = 31590036
59 + 31589977 = 31590036
83 + 31589953 = 31590036
113 + 31589923 = 31590036
167 + 31589869 = 31590036
193 + 31589843 = 31590036
263 + 31589773 = 31590036

Showing the first eight; more decompositions exist.
