Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747974, here are decompositions:

3 + 8747971 = 8747974
17 + 8747957 = 8747974
41 + 8747933 = 8747974
47 + 8747927 = 8747974
71 + 8747903 = 8747974
83 + 8747891 = 8747974
167 + 8747807 = 8747974
197 + 8747777 = 8747974

Showing the first eight; more decompositions exist.
