Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473252, here are decompositions:

11 + 31473241 = 31473252
43 + 31473209 = 31473252
61 + 31473191 = 31473252
79 + 31473173 = 31473252
89 + 31473163 = 31473252
101 + 31473151 = 31473252
191 + 31473061 = 31473252
211 + 31473041 = 31473252

Showing the first eight; more decompositions exist.
