Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611778, here are decompositions:

181 + 8611597 = 8611778
229 + 8611549 = 8611778
277 + 8611501 = 8611778
337 + 8611441 = 8611778
367 + 8611411 = 8611778
379 + 8611399 = 8611778
397 + 8611381 = 8611778
421 + 8611357 = 8611778

Showing the first eight; more decompositions exist.
