Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482188, here are decompositions:

19 + 31482169 = 31482188
151 + 31482037 = 31482188
277 + 31481911 = 31482188
337 + 31481851 = 31482188
421 + 31481767 = 31482188
457 + 31481731 = 31482188
487 + 31481701 = 31482188
691 + 31481497 = 31482188

Showing the first eight; more decompositions exist.
