Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90040, here are decompositions:

17 + 90023 = 90040
23 + 90017 = 90040
29 + 90011 = 90040
101 + 89939 = 90040
131 + 89909 = 90040
149 + 89891 = 90040
173 + 89867 = 90040
191 + 89849 = 90040

Showing the first eight; more decompositions exist.
