Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737858, here are decompositions:

29 + 8737829 = 8737858
149 + 8737709 = 8737858
191 + 8737667 = 8737858
281 + 8737577 = 8737858
431 + 8737427 = 8737858
509 + 8737349 = 8737858
557 + 8737301 = 8737858
587 + 8737271 = 8737858

Showing the first eight; more decompositions exist.
