Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610466, here are decompositions:

29 + 31610437 = 31610466
53 + 31610413 = 31610466
73 + 31610393 = 31610466
103 + 31610363 = 31610466
113 + 31610353 = 31610466
127 + 31610339 = 31610466
149 + 31610317 = 31610466
179 + 31610287 = 31610466

Showing the first eight; more decompositions exist.
