Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621270, here are decompositions:

61 + 8621209 = 8621270
127 + 8621143 = 8621270
181 + 8621089 = 8621270
193 + 8621077 = 8621270
223 + 8621047 = 8621270
277 + 8620993 = 8621270
373 + 8620897 = 8621270
397 + 8620873 = 8621270

Showing the first eight; more decompositions exist.
