Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497388, here are decompositions:

67 + 2147497321 = 2147497388
151 + 2147497237 = 2147497388
307 + 2147497081 = 2147497388
349 + 2147497039 = 2147497388
409 + 2147496979 = 2147497388
541 + 2147496847 = 2147497388
571 + 2147496817 = 2147497388
1039 + 2147496349 = 2147497388

Showing the first eight; more decompositions exist.
