Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446712, here are decompositions:

23 + 31446689 = 31446712
71 + 31446641 = 31446712
149 + 31446563 = 31446712
179 + 31446533 = 31446712
251 + 31446461 = 31446712
383 + 31446329 = 31446712
389 + 31446323 = 31446712
461 + 31446251 = 31446712

Showing the first eight; more decompositions exist.
