Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611272, here are decompositions:

11 + 8611261 = 8611272
23 + 8611249 = 8611272
53 + 8611219 = 8611272
71 + 8611201 = 8611272
139 + 8611133 = 8611272
239 + 8611033 = 8611272
269 + 8611003 = 8611272
311 + 8610961 = 8611272

Showing the first eight; more decompositions exist.
