Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987836, here are decompositions:

43 + 987793 = 987836
97 + 987739 = 987836
139 + 987697 = 987836
229 + 987607 = 987836
277 + 987559 = 987836
313 + 987523 = 987836
373 + 987463 = 987836
379 + 987457 = 987836

Showing the first eight; more decompositions exist.
