Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446766, here are decompositions:

5 + 31446761 = 31446766
17 + 31446749 = 31446766
23 + 31446743 = 31446766
173 + 31446593 = 31446766
233 + 31446533 = 31446766
443 + 31446323 = 31446766
509 + 31446257 = 31446766
599 + 31446167 = 31446766

Showing the first eight; more decompositions exist.
