Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611478, here are decompositions:

37 + 8611441 = 8611478
67 + 8611411 = 8611478
79 + 8611399 = 8611478
97 + 8611381 = 8611478
157 + 8611321 = 8611478
181 + 8611297 = 8611478
229 + 8611249 = 8611478
277 + 8611201 = 8611478

Showing the first eight; more decompositions exist.
