Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618842, here are decompositions:

53 + 8618789 = 8618842
59 + 8618783 = 8618842
83 + 8618759 = 8618842
251 + 8618591 = 8618842
359 + 8618483 = 8618842
503 + 8618339 = 8618842
569 + 8618273 = 8618842
599 + 8618243 = 8618842

Showing the first eight; more decompositions exist.
