Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472172, here are decompositions:

5 + 31472167 = 31472172
13 + 31472159 = 31472172
19 + 31472153 = 31472172
23 + 31472149 = 31472172
29 + 31472143 = 31472172
41 + 31472131 = 31472172
103 + 31472069 = 31472172
131 + 31472041 = 31472172

Showing the first eight; more decompositions exist.
