Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629402, here are decompositions:

53 + 8629349 = 8629402
59 + 8629343 = 8629402
233 + 8629169 = 8629402
263 + 8629139 = 8629402
293 + 8629109 = 8629402
479 + 8628923 = 8629402
503 + 8628899 = 8629402
773 + 8628629 = 8629402

Showing the first eight; more decompositions exist.
