Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473006, here are decompositions:

23 + 31472983 = 31473006
43 + 31472963 = 31473006
79 + 31472927 = 31473006
127 + 31472879 = 31473006
139 + 31472867 = 31473006
157 + 31472849 = 31473006
167 + 31472839 = 31473006
179 + 31472827 = 31473006

Showing the first eight; more decompositions exist.
