Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612170, here are decompositions:

3 + 8612167 = 8612170
71 + 8612099 = 8612170
113 + 8612057 = 8612170
131 + 8612039 = 8612170
137 + 8612033 = 8612170
179 + 8611991 = 8612170
311 + 8611859 = 8612170
449 + 8611721 = 8612170

Showing the first eight; more decompositions exist.
