Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493540, here are decompositions:

61 + 2147493479 = 2147493540
83 + 2147493457 = 2147493540
107 + 2147493433 = 2147493540
131 + 2147493409 = 2147493540
149 + 2147493391 = 2147493540
229 + 2147493311 = 2147493540
239 + 2147493301 = 2147493540
251 + 2147493289 = 2147493540

Showing the first eight; more decompositions exist.
