Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700500, here are decompositions:

43 + 8700457 = 8700500
79 + 8700421 = 8700500
139 + 8700361 = 8700500
307 + 8700193 = 8700500
331 + 8700169 = 8700500
379 + 8700121 = 8700500
421 + 8700079 = 8700500
463 + 8700037 = 8700500

Showing the first eight; more decompositions exist.
