Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446546, here are decompositions:

13 + 31446533 = 31446546
107 + 31446439 = 31446546
179 + 31446367 = 31446546
223 + 31446323 = 31446546
293 + 31446253 = 31446546
317 + 31446229 = 31446546
379 + 31446167 = 31446546
449 + 31446097 = 31446546

Showing the first eight; more decompositions exist.
