Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473798, here are decompositions:

17 + 31473781 = 31473798
19 + 31473779 = 31473798
199 + 31473599 = 31473798
269 + 31473529 = 31473798
311 + 31473487 = 31473798
401 + 31473397 = 31473798
439 + 31473359 = 31473798
467 + 31473331 = 31473798

Showing the first eight; more decompositions exist.
