Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611580, here are decompositions:

7 + 8611573 = 8611580
31 + 8611549 = 8611580
79 + 8611501 = 8611580
139 + 8611441 = 8611580
157 + 8611423 = 8611580
181 + 8611399 = 8611580
199 + 8611381 = 8611580
223 + 8611357 = 8611580

Showing the first eight; more decompositions exist.
