Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468984, here are decompositions:

  • 13 + 2147468971 = 2147468984
  • 61 + 2147468923 = 2147468984
  • 97 + 2147468887 = 2147468984
  • 103 + 2147468881 = 2147468984
  • 151 + 2147468833 = 2147468984
  • 181 + 2147468803 = 2147468984
  • 211 + 2147468773 = 2147468984
  • 421 + 2147468563 = 2147468984

Showing the first eight; more decompositions exist.
