Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473932, here are decompositions:

31 + 31473901 = 31473932
151 + 31473781 = 31473932
199 + 31473733 = 31473932
229 + 31473703 = 31473932
349 + 31473583 = 31473932
409 + 31473523 = 31473932
601 + 31473331 = 31473932
619 + 31473313 = 31473932

Showing the first eight; more decompositions exist.
