Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611290, here are decompositions:

7 + 8611283 = 8611290
29 + 8611261 = 8611290
41 + 8611249 = 8611290
43 + 8611247 = 8611290
71 + 8611219 = 8611290
89 + 8611201 = 8611290
109 + 8611181 = 8611290
139 + 8611151 = 8611290

Showing the first eight; more decompositions exist.
