Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634172, here are decompositions:

3 + 8634169 = 8634172
11 + 8634161 = 8634172
191 + 8633981 = 8634172
233 + 8633939 = 8634172
251 + 8633921 = 8634172
311 + 8633861 = 8634172
461 + 8633711 = 8634172
509 + 8633663 = 8634172

Showing the first eight; more decompositions exist.
