Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482576, here are decompositions:

7 + 31482569 = 31482576
17 + 31482559 = 31482576
67 + 31482509 = 31482576
137 + 31482439 = 31482576
149 + 31482427 = 31482576
227 + 31482349 = 31482576
233 + 31482343 = 31482576
239 + 31482337 = 31482576

Showing the first eight; more decompositions exist.
