Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90010, here are decompositions:

3 + 90007 = 90010
47 + 89963 = 90010
71 + 89939 = 90010
101 + 89909 = 90010
113 + 89897 = 90010
191 + 89819 = 90010
227 + 89783 = 90010
251 + 89759 = 90010

Showing the first eight; more decompositions exist.
