Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530346, here are decompositions:

5 + 31530341 = 31530346
53 + 31530293 = 31530346
149 + 31530197 = 31530346
173 + 31530173 = 31530346
317 + 31530029 = 31530346
503 + 31529843 = 31530346
563 + 31529783 = 31530346
677 + 31529669 = 31530346

Showing the first eight; more decompositions exist.
