Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462108, here are decompositions:

5 + 31462103 = 31462108
101 + 31462007 = 31462108
131 + 31461977 = 31462108
257 + 31461851 = 31462108
317 + 31461791 = 31462108
347 + 31461761 = 31462108
467 + 31461641 = 31462108
827 + 31461281 = 31462108

Showing the first eight; more decompositions exist.
