Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743158, here are decompositions:

19 + 8743139 = 8743158
37 + 8743121 = 8743158
59 + 8743099 = 8743158
71 + 8743087 = 8743158
79 + 8743079 = 8743158
131 + 8743027 = 8743158
139 + 8743019 = 8743158
157 + 8743001 = 8743158

Showing the first eight; more decompositions exist.
