Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40090, here are decompositions:

3 + 40087 = 40090
53 + 40037 = 40090
59 + 40031 = 40090
101 + 39989 = 40090
107 + 39983 = 40090
137 + 39953 = 40090
227 + 39863 = 40090
233 + 39857 = 40090

Showing the first eight; more decompositions exist.
