Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543176, here are decompositions:

13 + 31543163 = 31543176
43 + 31543133 = 31543176
73 + 31543103 = 31543176
97 + 31543079 = 31543176
107 + 31543069 = 31543176
109 + 31543067 = 31543176
157 + 31543019 = 31543176
167 + 31543009 = 31543176

Showing the first eight; more decompositions exist.
