Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452450, here are decompositions:

31 + 31452419 = 31452450
83 + 31452367 = 31452450
109 + 31452341 = 31452450
149 + 31452301 = 31452450
167 + 31452283 = 31452450
241 + 31452209 = 31452450
251 + 31452199 = 31452450
269 + 31452181 = 31452450

Showing the first eight; more decompositions exist.
