Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452652, here are decompositions:

3 + 31452649 = 31452652
29 + 31452623 = 31452652
53 + 31452599 = 31452652
113 + 31452539 = 31452652
131 + 31452521 = 31452652
191 + 31452461 = 31452652
233 + 31452419 = 31452652
251 + 31452401 = 31452652

Showing the first eight; more decompositions exist.
