Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618048, here are decompositions:

7 + 8618041 = 8618048
211 + 8617837 = 8618048
349 + 8617699 = 8618048
367 + 8617681 = 8618048
421 + 8617627 = 8618048
487 + 8617561 = 8618048
499 + 8617549 = 8618048
601 + 8617447 = 8618048

Showing the first eight; more decompositions exist.
