Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463284, here are decompositions:

3 + 31463281 = 31463284
23 + 31463261 = 31463284
71 + 31463213 = 31463284
137 + 31463147 = 31463284
197 + 31463087 = 31463284
353 + 31462931 = 31463284
383 + 31462901 = 31463284
491 + 31462793 = 31463284

Showing the first eight; more decompositions exist.
