Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476278, here are decompositions:

109 + 31476169 = 31476278
181 + 31476097 = 31476278
349 + 31475929 = 31476278
367 + 31475911 = 31476278
499 + 31475779 = 31476278
601 + 31475677 = 31476278
787 + 31475491 = 31476278
877 + 31475401 = 31476278

Showing the first eight; more decompositions exist.
