Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610140, here are decompositions:

3 + 8610137 = 8610140
73 + 8610067 = 8610140
79 + 8610061 = 8610140
139 + 8610001 = 8610140
223 + 8609917 = 8610140
229 + 8609911 = 8610140
241 + 8609899 = 8610140
307 + 8609833 = 8610140

Showing the first eight; more decompositions exist.
