Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488186, here are decompositions:

23 + 2147488163 = 2147488186
317 + 2147487869 = 2147488186
353 + 2147487833 = 2147488186
359 + 2147487827 = 2147488186
383 + 2147487803 = 2147488186
563 + 2147487623 = 2147488186
587 + 2147487599 = 2147488186
677 + 2147487509 = 2147488186

Showing the first eight; more decompositions exist.
