Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618012, here are decompositions:

19 + 8617993 = 8618012
79 + 8617933 = 8618012
313 + 8617699 = 8618012
331 + 8617681 = 8618012
463 + 8617549 = 8618012
499 + 8617513 = 8618012
631 + 8617381 = 8618012
751 + 8617261 = 8618012

Showing the first eight; more decompositions exist.
