Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482530, here are decompositions:

19 + 31482511 = 31482530
31 + 31482499 = 31482530
103 + 31482427 = 31482530
181 + 31482349 = 31482530
193 + 31482337 = 31482530
223 + 31482307 = 31482530
283 + 31482247 = 31482530
433 + 31482097 = 31482530

Showing the first eight; more decompositions exist.
