Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485840, here are decompositions:

11 + 2147485829 = 2147485840
23 + 2147485817 = 2147485840
167 + 2147485673 = 2147485840
191 + 2147485649 = 2147485840
281 + 2147485559 = 2147485840
293 + 2147485547 = 2147485840
317 + 2147485523 = 2147485840
389 + 2147485451 = 2147485840

Showing the first eight; more decompositions exist.
