Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734180, here are decompositions:

11 + 8734169 = 8734180
101 + 8734079 = 8734180
167 + 8734013 = 8734180
179 + 8734001 = 8734180
239 + 8733941 = 8734180
251 + 8733929 = 8734180
281 + 8733899 = 8734180
347 + 8733833 = 8734180

Showing the first eight; more decompositions exist.
