Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619266, here are decompositions:

3 + 8619263 = 8619266
37 + 8619229 = 8619266
43 + 8619223 = 8619266
67 + 8619199 = 8619266
109 + 8619157 = 8619266
199 + 8619067 = 8619266
307 + 8618959 = 8619266
349 + 8618917 = 8619266

Showing the first eight; more decompositions exist.
