Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618626, here are decompositions:

59 + 8618567 = 8618626
197 + 8618429 = 8618626
239 + 8618387 = 8618626
353 + 8618273 = 8618626
383 + 8618243 = 8618626
389 + 8618237 = 8618626
479 + 8618147 = 8618626
563 + 8618063 = 8618626

Showing the first eight; more decompositions exist.
