Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626658, here are decompositions:

37 + 8626621 = 8626658
109 + 8626549 = 8626658
151 + 8626507 = 8626658
199 + 8626459 = 8626658
241 + 8626417 = 8626658
409 + 8626249 = 8626658
421 + 8626237 = 8626658
499 + 8626159 = 8626658

Showing the first eight; more decompositions exist.
