Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611372, here are decompositions:

23 + 8611349 = 8611372
41 + 8611331 = 8611372
71 + 8611301 = 8611372
89 + 8611283 = 8611372
191 + 8611181 = 8611372
233 + 8611139 = 8611372
239 + 8611133 = 8611372
479 + 8610893 = 8611372

Showing the first eight; more decompositions exist.
