Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604840, here are decompositions:

17 + 8604823 = 8604840
29 + 8604811 = 8604840
31 + 8604809 = 8604840
43 + 8604797 = 8604840
59 + 8604781 = 8604840
61 + 8604779 = 8604840
71 + 8604769 = 8604840
73 + 8604767 = 8604840

Showing the first eight; more decompositions exist.
