Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610500, here are decompositions:

107 + 31610393 = 31610500
137 + 31610363 = 31610500
167 + 31610333 = 31610500
263 + 31610237 = 31610500
269 + 31610231 = 31610500
359 + 31610141 = 31610500
419 + 31610081 = 31610500
461 + 31610039 = 31610500

Showing the first eight; more decompositions exist.
