Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740100, here are decompositions:

3 + 8740097 = 8740100
13 + 8740087 = 8740100
97 + 8740003 = 8740100
139 + 8739961 = 8740100
163 + 8739937 = 8740100
181 + 8739919 = 8740100
199 + 8739901 = 8740100
223 + 8739877 = 8740100

Showing the first eight; more decompositions exist.
