Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493628, here are decompositions:

11 + 2147493617 = 2147493628
29 + 2147493599 = 2147493628
149 + 2147493479 = 2147493628
317 + 2147493311 = 2147493628
347 + 2147493281 = 2147493628
509 + 2147493119 = 2147493628
887 + 2147492741 = 2147493628
1019 + 2147492609 = 2147493628

Showing the first eight; more decompositions exist.
