Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500466, here are decompositions:

3 + 31500463 = 31500466
47 + 31500419 = 31500466
59 + 31500407 = 31500466
83 + 31500383 = 31500466
89 + 31500377 = 31500466
113 + 31500353 = 31500466
269 + 31500197 = 31500466
317 + 31500149 = 31500466

Showing the first eight; more decompositions exist.
