Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468876, here are decompositions:

  • 43 + 2147468833 = 2147468876
  • 67 + 2147468809 = 2147468876
  • 73 + 2147468803 = 2147468876
  • 97 + 2147468779 = 2147468876
  • 103 + 2147468773 = 2147468876
  • 277 + 2147468599 = 2147468876
  • 313 + 2147468563 = 2147468876
  • 373 + 2147468503 = 2147468876

Showing the first eight; more decompositions exist.
