Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491694, here are decompositions:

3 + 2147491691 = 2147491694
97 + 2147491597 = 2147491694
151 + 2147491543 = 2147491694
157 + 2147491537 = 2147491694
277 + 2147491417 = 2147491694
421 + 2147491273 = 2147491694
433 + 2147491261 = 2147491694
457 + 2147491237 = 2147491694

Showing the first eight; more decompositions exist.
