Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473058, here are decompositions:

17 + 31473041 = 31473058
131 + 31472927 = 31473058
167 + 31472891 = 31473058
179 + 31472879 = 31473058
191 + 31472867 = 31473058
251 + 31472807 = 31473058
359 + 31472699 = 31473058
389 + 31472669 = 31473058

Showing the first eight; more decompositions exist.
