Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462100, here are decompositions:

31 + 31462069 = 31462100
79 + 31462021 = 31462100
97 + 31462003 = 31462100
139 + 31461961 = 31462100
151 + 31461949 = 31462100
157 + 31461943 = 31462100
181 + 31461919 = 31462100
277 + 31461823 = 31462100

Showing the first eight; more decompositions exist.
