Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473254, here are decompositions:

3 + 31473251 = 31473254
13 + 31473241 = 31473254
37 + 31473217 = 31473254
67 + 31473187 = 31473254
103 + 31473151 = 31473254
193 + 31473061 = 31473254
223 + 31473031 = 31473254
271 + 31472983 = 31473254

Showing the first eight; more decompositions exist.
