Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611142, here are decompositions:

3 + 8611139 = 8611142
79 + 8611063 = 8611142
109 + 8611033 = 8611142
139 + 8611003 = 8611142
181 + 8610961 = 8611142
223 + 8610919 = 8611142
229 + 8610913 = 8611142
271 + 8610871 = 8611142

Showing the first eight; more decompositions exist.
