Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611488, here are decompositions:

47 + 8611441 = 8611488
89 + 8611399 = 8611488
107 + 8611381 = 8611488
131 + 8611357 = 8611488
139 + 8611349 = 8611488
157 + 8611331 = 8611488
167 + 8611321 = 8611488
181 + 8611307 = 8611488

Showing the first eight; more decompositions exist.
