Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446916, here are decompositions:

23 + 31446893 = 31446916
167 + 31446749 = 31446916
173 + 31446743 = 31446916
227 + 31446689 = 31446916
353 + 31446563 = 31446916
359 + 31446557 = 31446916
383 + 31446533 = 31446916
587 + 31446329 = 31446916

Showing the first eight; more decompositions exist.
