Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740146, here are decompositions:

7 + 8740139 = 8740146
17 + 8740129 = 8740146
29 + 8740117 = 8740146
59 + 8740087 = 8740146
109 + 8740037 = 8740146
179 + 8739967 = 8740146
193 + 8739953 = 8740146
227 + 8739919 = 8740146

Showing the first eight; more decompositions exist.
