Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611658, here are decompositions:

61 + 8611597 = 8611658
109 + 8611549 = 8611658
127 + 8611531 = 8611658
157 + 8611501 = 8611658
277 + 8611381 = 8611658
337 + 8611321 = 8611658
397 + 8611261 = 8611658
409 + 8611249 = 8611658

Showing the first eight; more decompositions exist.
