Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544766, here are decompositions:

7 + 31544759 = 31544766
17 + 31544749 = 31544766
47 + 31544719 = 31544766
53 + 31544713 = 31544766
109 + 31544657 = 31544766
179 + 31544587 = 31544766
193 + 31544573 = 31544766
223 + 31544543 = 31544766

Showing the first eight; more decompositions exist.
