Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617970, here are decompositions:

37 + 8617933 = 8617970
43 + 8617927 = 8617970
271 + 8617699 = 8617970
409 + 8617561 = 8617970
421 + 8617549 = 8617970
457 + 8617513 = 8617970
523 + 8617447 = 8617970
643 + 8617327 = 8617970

Showing the first eight; more decompositions exist.
