Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497492, here are decompositions:

3 + 2147497489 = 2147497492
11 + 2147497481 = 2147497492
89 + 2147497403 = 2147497492
131 + 2147497361 = 2147497492
359 + 2147497133 = 2147497492
449 + 2147497043 = 2147497492
521 + 2147496971 = 2147497492
653 + 2147496839 = 2147497492

Showing the first eight; more decompositions exist.
