Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618782, here are decompositions:

23 + 8618759 = 8618782
83 + 8618699 = 8618782
101 + 8618681 = 8618782
191 + 8618591 = 8618782
281 + 8618501 = 8618782
353 + 8618429 = 8618782
443 + 8618339 = 8618782
509 + 8618273 = 8618782

Showing the first eight; more decompositions exist.
