Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746566, here are decompositions:

47 + 8746519 = 8746566
53 + 8746513 = 8746566
97 + 8746469 = 8746566
107 + 8746459 = 8746566
113 + 8746453 = 8746566
139 + 8746427 = 8746566
167 + 8746399 = 8746566
197 + 8746369 = 8746566

Showing the first eight; more decompositions exist.
