Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720176, here are decompositions:

5 + 8720171 = 8720176
89 + 8720087 = 8720176
149 + 8720027 = 8720176
233 + 8719943 = 8720176
359 + 8719817 = 8720176
599 + 8719577 = 8720176
797 + 8719379 = 8720176
809 + 8719367 = 8720176

Showing the first eight; more decompositions exist.
