Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473320, here are decompositions:

7 + 31473313 = 31473320
37 + 31473283 = 31473320
79 + 31473241 = 31473320
103 + 31473217 = 31473320
157 + 31473163 = 31473320
211 + 31473109 = 31473320
283 + 31473037 = 31473320
337 + 31472983 = 31473320

Showing the first eight; more decompositions exist.
