Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473324, here are decompositions:

11 + 31473313 = 31473324
41 + 31473283 = 31473324
61 + 31473263 = 31473324
73 + 31473251 = 31473324
83 + 31473241 = 31473324
107 + 31473217 = 31473324
137 + 31473187 = 31473324
151 + 31473173 = 31473324

Showing the first eight; more decompositions exist.
