Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476200, here are decompositions:

13 + 31476187 = 31476200
31 + 31476169 = 31476200
43 + 31476157 = 31476200
103 + 31476097 = 31476200
127 + 31476073 = 31476200
271 + 31475929 = 31476200
373 + 31475827 = 31476200
421 + 31475779 = 31476200

Showing the first eight; more decompositions exist.
