Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472162, here are decompositions:

3 + 31472159 = 31472162
13 + 31472149 = 31472162
19 + 31472143 = 31472162
31 + 31472131 = 31472162
109 + 31472053 = 31472162
151 + 31472011 = 31472162
223 + 31471939 = 31472162
229 + 31471933 = 31472162

Showing the first eight; more decompositions exist.
