Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738212, here are decompositions:

3 + 8738209 = 8738212
11 + 8738201 = 8738212
83 + 8738129 = 8738212
89 + 8738123 = 8738212
179 + 8738033 = 8738212
233 + 8737979 = 8738212
269 + 8737943 = 8738212
383 + 8737829 = 8738212

Showing the first eight; more decompositions exist.
