Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497874, here are decompositions:

103 + 2147497771 = 2147497874
157 + 2147497717 = 2147497874
211 + 2147497663 = 2147497874
367 + 2147497507 = 2147497874
463 + 2147497411 = 2147497874
631 + 2147497243 = 2147497874
673 + 2147497201 = 2147497874
733 + 2147497141 = 2147497874

Showing the first eight; more decompositions exist.
