Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462152, here are decompositions:

11 + 31462141 = 31462152
19 + 31462133 = 31462152
83 + 31462069 = 31462152
131 + 31462021 = 31462152
149 + 31462003 = 31462152
173 + 31461979 = 31462152
191 + 31461961 = 31462152
229 + 31461923 = 31462152

Showing the first eight; more decompositions exist.
