Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628406, here are decompositions:

23 + 8628383 = 8628406
29 + 8628377 = 8628406
47 + 8628359 = 8628406
53 + 8628353 = 8628406
113 + 8628293 = 8628406
173 + 8628233 = 8628406
233 + 8628173 = 8628406
257 + 8628149 = 8628406

Showing the first eight; more decompositions exist.
