Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491874, here are decompositions:

37 + 2147491837 = 2147491874
43 + 2147491831 = 2147491874
271 + 2147491603 = 2147491874
277 + 2147491597 = 2147491874
331 + 2147491543 = 2147491874
337 + 2147491537 = 2147491874
397 + 2147491477 = 2147491874
457 + 2147491417 = 2147491874

Showing the first eight; more decompositions exist.
