Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446284, here are decompositions:

31 + 31446253 = 31446284
43 + 31446241 = 31446284
61 + 31446223 = 31446284
73 + 31446211 = 31446284
151 + 31446133 = 31446284
223 + 31446061 = 31446284
307 + 31445977 = 31446284
367 + 31445917 = 31446284

Showing the first eight; more decompositions exist.
