Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503384, here are decompositions:

5 + 31503379 = 31503384
23 + 31503361 = 31503384
41 + 31503343 = 31503384
43 + 31503341 = 31503384
47 + 31503337 = 31503384
53 + 31503331 = 31503384
61 + 31503323 = 31503384
71 + 31503313 = 31503384

Showing the first eight; more decompositions exist.
