Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618948, here are decompositions:

31 + 8618917 = 8618948
97 + 8618851 = 8618948
139 + 8618809 = 8618948
199 + 8618749 = 8618948
211 + 8618737 = 8618948
367 + 8618581 = 8618948
571 + 8618377 = 8618948
619 + 8618329 = 8618948

Showing the first eight; more decompositions exist.
