Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610480, here are decompositions:

43 + 31610437 = 31610480
67 + 31610413 = 31610480
127 + 31610353 = 31610480
163 + 31610317 = 31610480
193 + 31610287 = 31610480
211 + 31610269 = 31610480
283 + 31610197 = 31610480
337 + 31610143 = 31610480

Showing the first eight; more decompositions exist.
