Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611670, here are decompositions:

3 + 8611667 = 8611670
7 + 8611663 = 8611670
37 + 8611633 = 8611670
73 + 8611597 = 8611670
97 + 8611573 = 8611670
139 + 8611531 = 8611670
229 + 8611441 = 8611670
271 + 8611399 = 8611670

Showing the first eight; more decompositions exist.
