Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700392, here are decompositions:

31 + 8700361 = 8700392
109 + 8700283 = 8700392
139 + 8700253 = 8700392
199 + 8700193 = 8700392
223 + 8700169 = 8700392
271 + 8700121 = 8700392
313 + 8700079 = 8700392
373 + 8700019 = 8700392

Showing the first eight; more decompositions exist.
