Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498484, here are decompositions:

13 + 31498471 = 31498484
211 + 31498273 = 31498484
271 + 31498213 = 31498484
373 + 31498111 = 31498484
397 + 31498087 = 31498484
487 + 31497997 = 31498484
601 + 31497883 = 31498484
613 + 31497871 = 31498484

Showing the first eight; more decompositions exist.
