Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552752, here are decompositions:

5 + 31552747 = 31552752
19 + 31552733 = 31552752
31 + 31552721 = 31552752
43 + 31552709 = 31552752
59 + 31552693 = 31552752
71 + 31552681 = 31552752
109 + 31552643 = 31552752
113 + 31552639 = 31552752

Showing the first eight; more decompositions exist.
