Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476290, here are decompositions:

7 + 31476283 = 31476290
103 + 31476187 = 31476290
193 + 31476097 = 31476290
277 + 31476013 = 31476290
337 + 31475953 = 31476290
379 + 31475911 = 31476290
463 + 31475827 = 31476290
541 + 31475749 = 31476290

Showing the first eight; more decompositions exist.
