Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624668, here are decompositions:

47 + 8624621 = 8624668
191 + 8624477 = 8624668
401 + 8624267 = 8624668
419 + 8624249 = 8624668
431 + 8624237 = 8624668
467 + 8624201 = 8624668
491 + 8624177 = 8624668
509 + 8624159 = 8624668

Showing the first eight; more decompositions exist.
