Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691842, here are decompositions:

43 + 8691799 = 8691842
79 + 8691763 = 8691842
109 + 8691733 = 8691842
199 + 8691643 = 8691842
373 + 8691469 = 8691842
409 + 8691433 = 8691842
613 + 8691229 = 8691842
619 + 8691223 = 8691842

Showing the first eight; more decompositions exist.
