Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611772, here are decompositions:

109 + 8611663 = 8611772
139 + 8611633 = 8611772
199 + 8611573 = 8611772
223 + 8611549 = 8611772
241 + 8611531 = 8611772
271 + 8611501 = 8611772
331 + 8611441 = 8611772
349 + 8611423 = 8611772

Showing the first eight; more decompositions exist.
