Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473928, here are decompositions:

11 + 31473917 = 31473928
41 + 31473887 = 31473928
89 + 31473839 = 31473928
149 + 31473779 = 31473928
347 + 31473581 = 31473928
449 + 31473479 = 31473928
491 + 31473437 = 31473928
569 + 31473359 = 31473928

Showing the first eight; more decompositions exist.
