Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467954, here are decompositions:

  • 83 + 2147467871 = 2147467954
  • 257 + 2147467697 = 2147467954
  • 461 + 2147467493 = 2147467954
  • 491 + 2147467463 = 2147467954
  • 587 + 2147467367 = 2147467954
  • 743 + 2147467211 = 2147467954
  • 887 + 2147467067 = 2147467954
  • 911 + 2147467043 = 2147467954

Showing the first eight; more decompositions exist.
