Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749186, here are decompositions:

23 + 8749163 = 8749186
53 + 8749133 = 8749186
59 + 8749127 = 8749186
137 + 8749049 = 8749186
167 + 8749019 = 8749186
179 + 8749007 = 8749186
197 + 8748989 = 8749186
233 + 8748953 = 8749186

Showing the first eight; more decompositions exist.
