Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486140, here are decompositions:

11 + 2147486129 = 2147486140
29 + 2147486111 = 2147486140
131 + 2147486009 = 2147486140
227 + 2147485913 = 2147486140
251 + 2147485889 = 2147486140
263 + 2147485877 = 2147486140
269 + 2147485871 = 2147486140
281 + 2147485859 = 2147486140

Showing the first eight; more decompositions exist.
