Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612172, here are decompositions:

5 + 8612167 = 8612172
53 + 8612119 = 8612172
73 + 8612099 = 8612172
83 + 8612089 = 8612172
113 + 8612059 = 8612172
139 + 8612033 = 8612172
181 + 8611991 = 8612172
211 + 8611961 = 8612172

Showing the first eight; more decompositions exist.
