Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666354, here are decompositions:

3 + 8666351 = 8666354
7 + 8666347 = 8666354
31 + 8666323 = 8666354
181 + 8666173 = 8666354
331 + 8666023 = 8666354
337 + 8666017 = 8666354
421 + 8665933 = 8666354
457 + 8665897 = 8666354

Showing the first eight; more decompositions exist.
