Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482520, here are decompositions:

11 + 31482509 = 31482520
131 + 31482389 = 31482520
227 + 31482293 = 31482520
239 + 31482281 = 31482520
263 + 31482257 = 31482520
347 + 31482173 = 31482520
353 + 31482167 = 31482520
401 + 31482119 = 31482520

Showing the first eight; more decompositions exist.
