Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476398, here are decompositions:

7 + 31476391 = 31476398
211 + 31476187 = 31476398
229 + 31476169 = 31476398
241 + 31476157 = 31476398
367 + 31476031 = 31476398
487 + 31475911 = 31476398
571 + 31475827 = 31476398
601 + 31475797 = 31476398

Showing the first eight; more decompositions exist.
