Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473420, here are decompositions:

7 + 31473413 = 31473420
23 + 31473397 = 31473420
61 + 31473359 = 31473420
89 + 31473331 = 31473420
107 + 31473313 = 31473420
137 + 31473283 = 31473420
157 + 31473263 = 31473420
179 + 31473241 = 31473420

Showing the first eight; more decompositions exist.
