Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611442, here are decompositions:

3 + 8611439 = 8611442
19 + 8611423 = 8611442
31 + 8611411 = 8611442
43 + 8611399 = 8611442
61 + 8611381 = 8611442
139 + 8611303 = 8611442
181 + 8611261 = 8611442
193 + 8611249 = 8611442

Showing the first eight; more decompositions exist.
