Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493420, here are decompositions:

11 + 2147493409 = 2147493420
29 + 2147493391 = 2147493420
109 + 2147493311 = 2147493420
131 + 2147493289 = 2147493420
139 + 2147493281 = 2147493420
179 + 2147493241 = 2147493420
251 + 2147493169 = 2147493420
311 + 2147493109 = 2147493420

Showing the first eight; more decompositions exist.
