Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452550, here are decompositions:

11 + 31452539 = 31452550
23 + 31452527 = 31452550
29 + 31452521 = 31452550
53 + 31452497 = 31452550
89 + 31452461 = 31452550
131 + 31452419 = 31452550
149 + 31452401 = 31452550
317 + 31452233 = 31452550

Showing the first eight; more decompositions exist.
