Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473944, here are decompositions:

13 + 31473931 = 31473944
37 + 31473907 = 31473944
43 + 31473901 = 31473944
97 + 31473847 = 31473944
163 + 31473781 = 31473944
211 + 31473733 = 31473944
241 + 31473703 = 31473944
421 + 31473523 = 31473944

Showing the first eight; more decompositions exist.
