Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473016, here are decompositions:

53 + 31472963 = 31473016
89 + 31472927 = 31473016
137 + 31472879 = 31473016
149 + 31472867 = 31473016
167 + 31472849 = 31473016
293 + 31472723 = 31473016
317 + 31472699 = 31473016
347 + 31472669 = 31473016

Showing the first eight; more decompositions exist.
