Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90012, here are decompositions:

5 + 90007 = 90012
11 + 90001 = 90012
23 + 89989 = 90012
29 + 89983 = 90012
53 + 89959 = 90012
73 + 89939 = 90012
89 + 89923 = 90012
103 + 89909 = 90012

Showing the first eight; more decompositions exist.
