Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611278, here are decompositions:

17 + 8611261 = 8611278
29 + 8611249 = 8611278
31 + 8611247 = 8611278
59 + 8611219 = 8611278
97 + 8611181 = 8611278
127 + 8611151 = 8611278
131 + 8611147 = 8611278
139 + 8611139 = 8611278

Showing the first eight; more decompositions exist.
