Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476138, here are decompositions:

19 + 31476119 = 31476138
41 + 31476097 = 31476138
79 + 31476059 = 31476138
107 + 31476031 = 31476138
227 + 31475911 = 31476138
229 + 31475909 = 31476138
311 + 31475827 = 31476138
359 + 31475779 = 31476138

Showing the first eight; more decompositions exist.
