Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611662, here are decompositions:

19 + 8611643 = 8611662
29 + 8611633 = 8611662
43 + 8611619 = 8611662
61 + 8611601 = 8611662
89 + 8611573 = 8611662
113 + 8611549 = 8611662
131 + 8611531 = 8611662
139 + 8611523 = 8611662

Showing the first eight; more decompositions exist.
