Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611730, here are decompositions:

7 + 8611723 = 8611730
67 + 8611663 = 8611730
97 + 8611633 = 8611730
157 + 8611573 = 8611730
181 + 8611549 = 8611730
199 + 8611531 = 8611730
229 + 8611501 = 8611730
307 + 8611423 = 8611730

Showing the first eight; more decompositions exist.
