Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473368, here are decompositions:

37 + 31473331 = 31473368
127 + 31473241 = 31473368
151 + 31473217 = 31473368
181 + 31473187 = 31473368
307 + 31473061 = 31473368
331 + 31473037 = 31473368
337 + 31473031 = 31473368
439 + 31472929 = 31473368

Showing the first eight; more decompositions exist.
