Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747146, here are decompositions:

53 + 8747093 = 8747146
167 + 8746979 = 8747146
179 + 8746967 = 8747146
197 + 8746949 = 8747146
227 + 8746919 = 8747146
347 + 8746799 = 8747146
389 + 8746757 = 8747146
449 + 8746697 = 8747146

Showing the first eight; more decompositions exist.
