Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610450, here are decompositions:

13 + 31610437 = 31610450
37 + 31610413 = 31610450
61 + 31610389 = 31610450
97 + 31610353 = 31610450
163 + 31610287 = 31610450
181 + 31610269 = 31610450
307 + 31610143 = 31610450
337 + 31610113 = 31610450

Showing the first eight; more decompositions exist.
