Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700458, here are decompositions:

37 + 8700421 = 8700458
97 + 8700361 = 8700458
337 + 8700121 = 8700458
379 + 8700079 = 8700458
421 + 8700037 = 8700458
439 + 8700019 = 8700458
457 + 8700001 = 8700458
499 + 8699959 = 8700458

Showing the first eight; more decompositions exist.
