Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618038, here are decompositions:

5 + 8618033 = 8618038
17 + 8618021 = 8618038
47 + 8617991 = 8618038
89 + 8617949 = 8618038
167 + 8617871 = 8618038
239 + 8617799 = 8618038
251 + 8617787 = 8618038
269 + 8617769 = 8618038

Showing the first eight; more decompositions exist.
