Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670380, here are decompositions:

7 + 8670373 = 8670380
67 + 8670313 = 8670380
79 + 8670301 = 8670380
223 + 8670157 = 8670380
349 + 8670031 = 8670380
373 + 8670007 = 8670380
457 + 8669923 = 8670380
487 + 8669893 = 8670380

Showing the first eight; more decompositions exist.
