Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621354, here are decompositions:

73 + 8621281 = 8621354
211 + 8621143 = 8621354
271 + 8621083 = 8621354
277 + 8621077 = 8621354
307 + 8621047 = 8621354
337 + 8621017 = 8621354
457 + 8620897 = 8621354
607 + 8620747 = 8621354

Showing the first eight; more decompositions exist.
