Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497748, here are decompositions:

31 + 2147497717 = 2147497748
241 + 2147497507 = 2147497748
337 + 2147497411 = 2147497748
547 + 2147497201 = 2147497748
607 + 2147497141 = 2147497748
709 + 2147497039 = 2147497748
751 + 2147496997 = 2147497748
769 + 2147496979 = 2147497748

Showing the first eight; more decompositions exist.
