Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931530, here are decompositions:

13 + 931517 = 931530
31 + 931499 = 931530
43 + 931487 = 931530
109 + 931421 = 931530
113 + 931417 = 931530
167 + 931363 = 931530
179 + 931351 = 931530
211 + 931319 = 931530

Showing the first eight; more decompositions exist.
