Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701216, here are decompositions:

5 + 8701211 = 8701216
23 + 8701193 = 8701216
53 + 8701163 = 8701216
149 + 8701067 = 8701216
263 + 8700953 = 8701216
269 + 8700947 = 8701216
347 + 8700869 = 8701216
383 + 8700833 = 8701216

Showing the first eight; more decompositions exist.
