Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611578, here are decompositions:

5 + 8611573 = 8611578
29 + 8611549 = 8611578
47 + 8611531 = 8611578
137 + 8611441 = 8611578
139 + 8611439 = 8611578
167 + 8611411 = 8611578
179 + 8611399 = 8611578
197 + 8611381 = 8611578

Showing the first eight; more decompositions exist.
