Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489498, here are decompositions:

61 + 2147489437 = 2147489498
97 + 2147489401 = 2147489498
151 + 2147489347 = 2147489498
199 + 2147489299 = 2147489498
409 + 2147489089 = 2147489498
421 + 2147489077 = 2147489498
439 + 2147489059 = 2147489498
631 + 2147488867 = 2147489498

Showing the first eight; more decompositions exist.
