Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618266, here are decompositions:

23 + 8618243 = 8618266
29 + 8618237 = 8618266
53 + 8618213 = 8618266
179 + 8618087 = 8618266
233 + 8618033 = 8618266
317 + 8617949 = 8618266
389 + 8617877 = 8618266
443 + 8617823 = 8618266

Showing the first eight; more decompositions exist.
