Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468170, here are decompositions:

  • 101 + 2147468069 = 2147468170
  • 167 + 2147468003 = 2147468170
  • 251 + 2147467919 = 2147468170
  • 401 + 2147467769 = 2147468170
  • 503 + 2147467667 = 2147468170
  • 587 + 2147467583 = 2147468170
  • 677 + 2147467493 = 2147468170
  • 839 + 2147467331 = 2147468170

Showing the first eight; more decompositions exist.
