Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462082, here are decompositions:

13 + 31462069 = 31462082
61 + 31462021 = 31462082
79 + 31462003 = 31462082
103 + 31461979 = 31462082
139 + 31461943 = 31462082
163 + 31461919 = 31462082
241 + 31461841 = 31462082
271 + 31461811 = 31462082

Showing the first eight; more decompositions exist.
