Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473752, here are decompositions:

19 + 31473733 = 31473752
223 + 31473529 = 31473752
229 + 31473523 = 31473752
421 + 31473331 = 31473752
439 + 31473313 = 31473752
601 + 31473151 = 31473752
643 + 31473109 = 31473752
691 + 31473061 = 31473752

Showing the first eight; more decompositions exist.
