Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656658, here are decompositions:

97 + 8656561 = 8656658
181 + 8656477 = 8656658
337 + 8656321 = 8656658
379 + 8656279 = 8656658
487 + 8656171 = 8656658
499 + 8656159 = 8656658
541 + 8656117 = 8656658
601 + 8656057 = 8656658

Showing the first eight; more decompositions exist.
