Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706266, here are decompositions:

97 + 8706169 = 8706266
103 + 8706163 = 8706266
193 + 8706073 = 8706266
307 + 8705959 = 8706266
463 + 8705803 = 8706266
577 + 8705689 = 8706266
739 + 8705527 = 8706266
823 + 8705443 = 8706266

Showing the first eight; more decompositions exist.
