Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476500, here are decompositions:

43 + 31476457 = 31476500
67 + 31476433 = 31476500
109 + 31476391 = 31476500
127 + 31476373 = 31476500
151 + 31476349 = 31476500
157 + 31476343 = 31476500
313 + 31476187 = 31476500
331 + 31476169 = 31476500

Showing the first eight; more decompositions exist.
