Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491406, here are decompositions:

3 + 2147491403 = 2147491406
37 + 2147491369 = 2147491406
157 + 2147491249 = 2147491406
283 + 2147491123 = 2147491406
337 + 2147491069 = 2147491406
373 + 2147491033 = 2147491406
409 + 2147490997 = 2147491406
433 + 2147490973 = 2147491406

Showing the first eight; more decompositions exist.
