Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611472, here are decompositions:

31 + 8611441 = 8611472
61 + 8611411 = 8611472
73 + 8611399 = 8611472
151 + 8611321 = 8611472
211 + 8611261 = 8611472
223 + 8611249 = 8611472
271 + 8611201 = 8611472
409 + 8611063 = 8611472

Showing the first eight; more decompositions exist.
