Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751258, here are decompositions:

7 + 8751251 = 8751258
37 + 8751221 = 8751258
101 + 8751157 = 8751258
107 + 8751151 = 8751258
157 + 8751101 = 8751258
167 + 8751091 = 8751258
179 + 8751079 = 8751258
251 + 8751007 = 8751258

Showing the first eight; more decompositions exist.
