Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462000, here are decompositions:

23 + 31461977 = 31462000
107 + 31461893 = 31462000
113 + 31461887 = 31462000
149 + 31461851 = 31462000
239 + 31461761 = 31462000
257 + 31461743 = 31462000
263 + 31461737 = 31462000
347 + 31461653 = 31462000

Showing the first eight; more decompositions exist.
