Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661584, here are decompositions:

3 + 8661581 = 8661584
7 + 8661577 = 8661584
13 + 8661571 = 8661584
31 + 8661553 = 8661584
97 + 8661487 = 8661584
157 + 8661427 = 8661584
331 + 8661253 = 8661584
367 + 8661217 = 8661584

Showing the first eight; more decompositions exist.
