Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610300, here are decompositions:

13 + 31610287 = 31610300
31 + 31610269 = 31610300
103 + 31610197 = 31610300
157 + 31610143 = 31610300
193 + 31610107 = 31610300
277 + 31610023 = 31610300
307 + 31609993 = 31610300
367 + 31609933 = 31610300

Showing the first eight; more decompositions exist.
