Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446664, here are decompositions:

23 + 31446641 = 31446664
71 + 31446593 = 31446664
101 + 31446563 = 31446664
107 + 31446557 = 31446664
131 + 31446533 = 31446664
173 + 31446491 = 31446664
563 + 31446101 = 31446664
653 + 31446011 = 31446664

Showing the first eight; more decompositions exist.
