Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446346, here are decompositions:

5 + 31446341 = 31446346
17 + 31446329 = 31446346
23 + 31446323 = 31446346
89 + 31446257 = 31446346
179 + 31446167 = 31446346
293 + 31446053 = 31446346
389 + 31445957 = 31446346
557 + 31445789 = 31446346

Showing the first eight; more decompositions exist.
