Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618942, here are decompositions:

19 + 8618923 = 8618942
109 + 8618833 = 8618942
193 + 8618749 = 8618942
349 + 8618593 = 8618942
463 + 8618479 = 8618942
499 + 8618443 = 8618942
613 + 8618329 = 8618942
691 + 8618251 = 8618942

Showing the first eight; more decompositions exist.
