Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613518, here are decompositions:

37 + 8613481 = 8613518
61 + 8613457 = 8613518
79 + 8613439 = 8613518
97 + 8613421 = 8613518
127 + 8613391 = 8613518
139 + 8613379 = 8613518
307 + 8613211 = 8613518
337 + 8613181 = 8613518

Showing the first eight; more decompositions exist.
