Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482546, here are decompositions:

37 + 31482509 = 31482546
47 + 31482499 = 31482546
107 + 31482439 = 31482546
157 + 31482389 = 31482546
197 + 31482349 = 31482546
239 + 31482307 = 31482546
269 + 31482277 = 31482546
317 + 31482229 = 31482546

Showing the first eight; more decompositions exist.
