Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747130, here are decompositions:

11 + 8747119 = 8747130
19 + 8747111 = 8747130
37 + 8747093 = 8747130
47 + 8747083 = 8747130
59 + 8747071 = 8747130
89 + 8747041 = 8747130
131 + 8746999 = 8747130
151 + 8746979 = 8747130

Showing the first eight; more decompositions exist.
