Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613488, here are decompositions:

7 + 8613481 = 8613488
31 + 8613457 = 8613488
61 + 8613427 = 8613488
67 + 8613421 = 8613488
97 + 8613391 = 8613488
109 + 8613379 = 8613488
139 + 8613349 = 8613488
277 + 8613211 = 8613488

Showing the first eight; more decompositions exist.
