Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749158, here are decompositions:

7 + 8749151 = 8749158
17 + 8749141 = 8749158
31 + 8749127 = 8749158
37 + 8749121 = 8749158
71 + 8749087 = 8749158
109 + 8749049 = 8749158
139 + 8749019 = 8749158
151 + 8749007 = 8749158

Showing the first eight; more decompositions exist.
