Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452492, here are decompositions:

11 + 31452481 = 31452492
31 + 31452461 = 31452492
41 + 31452451 = 31452492
73 + 31452419 = 31452492
151 + 31452341 = 31452492
191 + 31452301 = 31452492
251 + 31452241 = 31452492
283 + 31452209 = 31452492

Showing the first eight; more decompositions exist.
