Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452532, here are decompositions:

3 + 31452529 = 31452532
5 + 31452527 = 31452532
11 + 31452521 = 31452532
71 + 31452461 = 31452532
113 + 31452419 = 31452532
131 + 31452401 = 31452532
191 + 31452341 = 31452532
359 + 31452173 = 31452532

Showing the first eight; more decompositions exist.
