Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446348, here are decompositions:

7 + 31446341 = 31446348
19 + 31446329 = 31446348
97 + 31446251 = 31446348
107 + 31446241 = 31446348
137 + 31446211 = 31446348
181 + 31446167 = 31446348
251 + 31446097 = 31446348
281 + 31446067 = 31446348

Showing the first eight; more decompositions exist.
