Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611956, here are decompositions:

53 + 8611903 = 8611956
83 + 8611873 = 8611956
97 + 8611859 = 8611956
107 + 8611849 = 8611956
109 + 8611847 = 8611956
127 + 8611829 = 8611956
137 + 8611819 = 8611956
163 + 8611793 = 8611956

Showing the first eight; more decompositions exist.
