Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492874, here are decompositions:

31 + 2147492843 = 2147492874
173 + 2147492701 = 2147492874
277 + 2147492597 = 2147492874
283 + 2147492591 = 2147492874
347 + 2147492527 = 2147492874
353 + 2147492521 = 2147492874
383 + 2147492491 = 2147492874
487 + 2147492387 = 2147492874

Showing the first eight; more decompositions exist.
