Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90038, here are decompositions:

7 + 90031 = 90038
19 + 90019 = 90038
31 + 90007 = 90038
37 + 90001 = 90038
61 + 89977 = 90038
79 + 89959 = 90038
139 + 89899 = 90038
199 + 89839 = 90038

Showing the first eight; more decompositions exist.
