Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488340, here are decompositions:

7 + 2147488333 = 2147488340
61 + 2147488279 = 2147488340
229 + 2147488111 = 2147488340
313 + 2147488027 = 2147488340
331 + 2147488009 = 2147488340
409 + 2147487931 = 2147488340
433 + 2147487907 = 2147488340
523 + 2147487817 = 2147488340

Showing the first eight; more decompositions exist.
