Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702212, here are decompositions:

5 + 8702207 = 8702212
23 + 8702189 = 8702212
53 + 8702159 = 8702212
149 + 8702063 = 8702212
251 + 8701961 = 8702212
263 + 8701949 = 8702212
359 + 8701853 = 8702212
401 + 8701811 = 8702212

Showing the first eight; more decompositions exist.
