Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468166, here are decompositions:

  • 47 + 2147468119 = 2147468166
  • 97 + 2147468069 = 2147468166
  • 163 + 2147468003 = 2147468166
  • 199 + 2147467967 = 2147468166
  • 353 + 2147467813 = 2147468166
  • 373 + 2147467793 = 2147468166
  • 397 + 2147467769 = 2147468166
  • 419 + 2147467747 = 2147468166

Showing the first eight; more decompositions exist.
