Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629730, here are decompositions:

19 + 8629711 = 8629730
79 + 8629651 = 8629730
223 + 8629507 = 8629730
283 + 8629447 = 8629730
397 + 8629333 = 8629730
433 + 8629297 = 8629730
607 + 8629123 = 8629730
643 + 8629087 = 8629730

Showing the first eight; more decompositions exist.
