Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628436, here are decompositions:

29 + 8628407 = 8628436
53 + 8628383 = 8628436
59 + 8628377 = 8628436
83 + 8628353 = 8628436
233 + 8628203 = 8628436
263 + 8628173 = 8628436
359 + 8628077 = 8628436
419 + 8628017 = 8628436

Showing the first eight; more decompositions exist.
