Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472884, here are decompositions:

5 + 31472879 = 31472884
17 + 31472867 = 31472884
71 + 31472813 = 31472884
251 + 31472633 = 31472884
293 + 31472591 = 31472884
347 + 31472537 = 31472884
383 + 31472501 = 31472884
593 + 31472291 = 31472884

Showing the first eight; more decompositions exist.
