Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452552, here are decompositions:

13 + 31452539 = 31452552
23 + 31452529 = 31452552
31 + 31452521 = 31452552
59 + 31452493 = 31452552
71 + 31452481 = 31452552
101 + 31452451 = 31452552
151 + 31452401 = 31452552
211 + 31452341 = 31452552

Showing the first eight; more decompositions exist.
