Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590086, here are decompositions:

79 + 31590007 = 31590086
103 + 31589983 = 31590086
109 + 31589977 = 31590086
163 + 31589923 = 31590086
313 + 31589773 = 31590086
349 + 31589737 = 31590086
379 + 31589707 = 31590086
547 + 31589539 = 31590086

Showing the first eight; more decompositions exist.
