Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661504, here are decompositions:

13 + 8661491 = 8661504
17 + 8661487 = 8661504
43 + 8661461 = 8661504
67 + 8661437 = 8661504
97 + 8661407 = 8661504
151 + 8661353 = 8661504
193 + 8661311 = 8661504
223 + 8661281 = 8661504

Showing the first eight; more decompositions exist.
