Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647346, here are decompositions:

73 + 8647273 = 8647346
163 + 8647183 = 8647346
223 + 8647123 = 8647346
283 + 8647063 = 8647346
397 + 8646949 = 8647346
457 + 8646889 = 8647346
523 + 8646823 = 8647346
739 + 8646607 = 8647346

Showing the first eight; more decompositions exist.
