Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444752, here are decompositions:

29 + 31444723 = 31444752
61 + 31444691 = 31444752
71 + 31444681 = 31444752
103 + 31444649 = 31444752
109 + 31444643 = 31444752
179 + 31444573 = 31444752
193 + 31444559 = 31444752
211 + 31444541 = 31444752

Showing the first eight; more decompositions exist.
