Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672212, here are decompositions:

5 + 8672207 = 8672212
11 + 8672201 = 8672212
113 + 8672099 = 8672212
149 + 8672063 = 8672212
233 + 8671979 = 8672212
293 + 8671919 = 8672212
401 + 8671811 = 8672212
443 + 8671769 = 8672212

Showing the first eight; more decompositions exist.
