Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473794, here are decompositions:

13 + 31473781 = 31473794
61 + 31473733 = 31473794
211 + 31473583 = 31473794
271 + 31473523 = 31473794
307 + 31473487 = 31473794
337 + 31473457 = 31473794
397 + 31473397 = 31473794
463 + 31473331 = 31473794

Showing the first eight; more decompositions exist.
