Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931512, here are decompositions:

13 + 931499 = 931512
149 + 931363 = 931512
193 + 931319 = 931512
199 + 931313 = 931512
223 + 931289 = 931512
271 + 931241 = 931512
313 + 931199 = 931512
331 + 931181 = 931512

Showing the first eight; more decompositions exist.
