Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473338, here are decompositions:

7 + 31473331 = 31473338
97 + 31473241 = 31473338
151 + 31473187 = 31473338
229 + 31473109 = 31473338
271 + 31473067 = 31473338
277 + 31473061 = 31473338
307 + 31473031 = 31473338
409 + 31472929 = 31473338

Showing the first eight; more decompositions exist.
