Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611590, here are decompositions:

17 + 8611573 = 8611590
41 + 8611549 = 8611590
59 + 8611531 = 8611590
61 + 8611529 = 8611590
67 + 8611523 = 8611590
89 + 8611501 = 8611590
103 + 8611487 = 8611590
149 + 8611441 = 8611590

Showing the first eight; more decompositions exist.
