Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620436, here are decompositions:

7 + 8620429 = 8620436
43 + 8620393 = 8620436
67 + 8620369 = 8620436
109 + 8620327 = 8620436
277 + 8620159 = 8620436
367 + 8620069 = 8620436
373 + 8620063 = 8620436
439 + 8619997 = 8620436

Showing the first eight; more decompositions exist.
