Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664658, here are decompositions:

131 + 8664527 = 8664658
227 + 8664431 = 8664658
239 + 8664419 = 8664658
269 + 8664389 = 8664658
281 + 8664377 = 8664658
347 + 8664311 = 8664658
797 + 8663861 = 8664658
839 + 8663819 = 8664658

Showing the first eight; more decompositions exist.
