Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671270, here are decompositions:

137 + 8671133 = 8671270
173 + 8671097 = 8671270
239 + 8671031 = 8671270
263 + 8671007 = 8671270
281 + 8670989 = 8671270
383 + 8670887 = 8671270
401 + 8670869 = 8671270
479 + 8670791 = 8671270

Showing the first eight; more decompositions exist.
