Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476538, here are decompositions:

29 + 31476509 = 31476538
89 + 31476449 = 31476538
101 + 31476437 = 31476538
167 + 31476371 = 31476538
389 + 31476149 = 31476538
419 + 31476119 = 31476538
479 + 31476059 = 31476538
521 + 31476017 = 31476538

Showing the first eight; more decompositions exist.
