Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618798, here are decompositions:

61 + 8618737 = 8618798
109 + 8618689 = 8618798
241 + 8618557 = 8618798
421 + 8618377 = 8618798
541 + 8618257 = 8618798
547 + 8618251 = 8618798
577 + 8618221 = 8618798
691 + 8618107 = 8618798

Showing the first eight; more decompositions exist.
