Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670278, here are decompositions:

151 + 8670127 = 8670278
241 + 8670037 = 8670278
271 + 8670007 = 8670278
349 + 8669929 = 8670278
367 + 8669911 = 8670278
457 + 8669821 = 8670278
577 + 8669701 = 8670278
607 + 8669671 = 8670278

Showing the first eight; more decompositions exist.
