Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736842, here are decompositions:

43 + 8736799 = 8736842
61 + 8736781 = 8736842
139 + 8736703 = 8736842
211 + 8736631 = 8736842
313 + 8736529 = 8736842
379 + 8736463 = 8736842
409 + 8736433 = 8736842
619 + 8736223 = 8736842

Showing the first eight; more decompositions exist.
