Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743170, here are decompositions:

31 + 8743139 = 8743170
67 + 8743103 = 8743170
71 + 8743099 = 8743170
83 + 8743087 = 8743170
103 + 8743067 = 8743170
127 + 8743043 = 8743170
151 + 8743019 = 8743170
173 + 8742997 = 8743170

Showing the first eight; more decompositions exist.
