Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687342, here are decompositions:

43 + 8687299 = 8687342
109 + 8687233 = 8687342
193 + 8687149 = 8687342
211 + 8687131 = 8687342
613 + 8686729 = 8687342
673 + 8686669 = 8687342
691 + 8686651 = 8687342
883 + 8686459 = 8687342

Showing the first eight; more decompositions exist.
