Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742836, here are decompositions:

19 + 8742817 = 8742836
97 + 8742739 = 8742836
163 + 8742673 = 8742836
199 + 8742637 = 8742836
307 + 8742529 = 8742836
337 + 8742499 = 8742836
367 + 8742469 = 8742836
373 + 8742463 = 8742836

Showing the first eight; more decompositions exist.
