Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607172, here are decompositions:

5 + 8607167 = 8607172
113 + 8607059 = 8607172
149 + 8607023 = 8607172
173 + 8606999 = 8607172
263 + 8606909 = 8607172
383 + 8606789 = 8607172
443 + 8606729 = 8607172
479 + 8606693 = 8607172

Showing the first eight; more decompositions exist.
