Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473342, here are decompositions:

11 + 31473331 = 31473342
29 + 31473313 = 31473342
59 + 31473283 = 31473342
79 + 31473263 = 31473342
101 + 31473241 = 31473342
139 + 31473203 = 31473342
151 + 31473191 = 31473342
179 + 31473163 = 31473342

Showing the first eight; more decompositions exist.
