Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619968, here are decompositions:

31 + 8619937 = 8619968
109 + 8619859 = 8619968
151 + 8619817 = 8619968
157 + 8619811 = 8619968
307 + 8619661 = 8619968
367 + 8619601 = 8619968
457 + 8619511 = 8619968
499 + 8619469 = 8619968

Showing the first eight; more decompositions exist.
