Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472166, here are decompositions:

7 + 31472159 = 31472166
13 + 31472153 = 31472166
17 + 31472149 = 31472166
23 + 31472143 = 31472166
43 + 31472123 = 31472166
59 + 31472107 = 31472166
97 + 31472069 = 31472166
113 + 31472053 = 31472166

Showing the first eight; more decompositions exist.
