Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618212, here are decompositions:

149 + 8618063 = 8618212
179 + 8618033 = 8618212
191 + 8618021 = 8618212
263 + 8617949 = 8618212
269 + 8617943 = 8618212
389 + 8617823 = 8618212
443 + 8617769 = 8618212
509 + 8617703 = 8618212

Showing the first eight; more decompositions exist.
