Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675840, here are decompositions:

7 + 8675833 = 8675840
73 + 8675767 = 8675840
97 + 8675743 = 8675840
163 + 8675677 = 8675840
331 + 8675509 = 8675840
337 + 8675503 = 8675840
367 + 8675473 = 8675840
457 + 8675383 = 8675840

Showing the first eight; more decompositions exist.
