Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611556, here are decompositions:

7 + 8611549 = 8611556
157 + 8611399 = 8611556
199 + 8611357 = 8611556
307 + 8611249 = 8611556
337 + 8611219 = 8611556
409 + 8611147 = 8611556
439 + 8611117 = 8611556
523 + 8611033 = 8611556

Showing the first eight; more decompositions exist.
