Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749170, here are decompositions:

7 + 8749163 = 8749170
19 + 8749151 = 8749170
29 + 8749141 = 8749170
37 + 8749133 = 8749170
43 + 8749127 = 8749170
83 + 8749087 = 8749170
151 + 8749019 = 8749170
163 + 8749007 = 8749170

Showing the first eight; more decompositions exist.
