Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611550, here are decompositions:

19 + 8611531 = 8611550
109 + 8611441 = 8611550
127 + 8611423 = 8611550
139 + 8611411 = 8611550
151 + 8611399 = 8611550
193 + 8611357 = 8611550
229 + 8611321 = 8611550
331 + 8611219 = 8611550

Showing the first eight; more decompositions exist.
