Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611972, here are decompositions:

3 + 8611969 = 8611972
11 + 8611961 = 8611972
113 + 8611859 = 8611972
179 + 8611793 = 8611972
251 + 8611721 = 8611972
263 + 8611709 = 8611972
269 + 8611703 = 8611972
293 + 8611679 = 8611972

Showing the first eight; more decompositions exist.
