Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740130, here are decompositions:

13 + 8740117 = 8740130
19 + 8740111 = 8740130
43 + 8740087 = 8740130
127 + 8740003 = 8740130
163 + 8739967 = 8740130
193 + 8739937 = 8740130
211 + 8739919 = 8740130
229 + 8739901 = 8740130

Showing the first eight; more decompositions exist.
