Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611378, here are decompositions:

29 + 8611349 = 8611378
47 + 8611331 = 8611378
71 + 8611307 = 8611378
131 + 8611247 = 8611378
197 + 8611181 = 8611378
227 + 8611151 = 8611378
239 + 8611139 = 8611378
641 + 8610737 = 8611378

Showing the first eight; more decompositions exist.
