Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670272, here are decompositions:

241 + 8670031 = 8670272
283 + 8669989 = 8670272
349 + 8669923 = 8670272
379 + 8669893 = 8670272
571 + 8669701 = 8670272
601 + 8669671 = 8670272
643 + 8669629 = 8670272
661 + 8669611 = 8670272

Showing the first eight; more decompositions exist.
