Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446964, here are decompositions:

11 + 31446953 = 31446964
47 + 31446917 = 31446964
71 + 31446893 = 31446964
401 + 31446563 = 31446964
431 + 31446533 = 31446964
503 + 31446461 = 31446964
641 + 31446323 = 31446964
797 + 31446167 = 31446964

Showing the first eight; more decompositions exist.
