Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611458, here are decompositions:

17 + 8611441 = 8611458
19 + 8611439 = 8611458
47 + 8611411 = 8611458
59 + 8611399 = 8611458
101 + 8611357 = 8611458
109 + 8611349 = 8611458
127 + 8611331 = 8611458
137 + 8611321 = 8611458

Showing the first eight; more decompositions exist.
