Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481624, here are decompositions:

3 + 31481621 = 31481624
103 + 31481521 = 31481624
127 + 31481497 = 31481624
151 + 31481473 = 31481624
193 + 31481431 = 31481624
241 + 31481383 = 31481624
271 + 31481353 = 31481624
283 + 31481341 = 31481624

Showing the first eight; more decompositions exist.
