Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611946, here are decompositions:

43 + 8611903 = 8611946
67 + 8611879 = 8611946
73 + 8611873 = 8611946
97 + 8611849 = 8611946
127 + 8611819 = 8611946
157 + 8611789 = 8611946
163 + 8611783 = 8611946
223 + 8611723 = 8611946

Showing the first eight; more decompositions exist.
