Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452424, here are decompositions:

5 + 31452419 = 31452424
23 + 31452401 = 31452424
83 + 31452341 = 31452424
191 + 31452233 = 31452424
251 + 31452173 = 31452424
293 + 31452131 = 31452424
383 + 31452041 = 31452424
431 + 31451993 = 31452424

Showing the first eight; more decompositions exist.
