Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446706, here are decompositions:

17 + 31446689 = 31446706
113 + 31446593 = 31446706
149 + 31446557 = 31446706
173 + 31446533 = 31446706
383 + 31446323 = 31446706
449 + 31446257 = 31446706
479 + 31446227 = 31446706
653 + 31446053 = 31446706

Showing the first eight; more decompositions exist.
