Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481348, here are decompositions:

7 + 31481341 = 31481348
97 + 31481251 = 31481348
109 + 31481239 = 31481348
271 + 31481077 = 31481348
337 + 31481011 = 31481348
487 + 31480861 = 31481348
499 + 31480849 = 31481348
709 + 31480639 = 31481348

Showing the first eight; more decompositions exist.
