Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625928, here are decompositions:

107 + 8625821 = 8625928
239 + 8625689 = 8625928
401 + 8625527 = 8625928
419 + 8625509 = 8625928
449 + 8625479 = 8625928
461 + 8625467 = 8625928
569 + 8625359 = 8625928
617 + 8625311 = 8625928

Showing the first eight; more decompositions exist.
