Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471376, here are decompositions:

3 + 31471373 = 31471376
19 + 31471357 = 31471376
163 + 31471213 = 31471376
229 + 31471147 = 31471376
283 + 31471093 = 31471376
379 + 31470997 = 31471376
463 + 31470913 = 31471376
487 + 31470889 = 31471376

Showing the first eight; more decompositions exist.
