Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497900, here are decompositions:

  • 11 + 2147497889 = 2147497900
  • 131 + 2147497769 = 2147497900
  • 167 + 2147497733 = 2147497900
  • 239 + 2147497661 = 2147497900
  • 419 + 2147497481 = 2147497900
  • 857 + 2147497043 = 2147497900
  • 881 + 2147497019 = 2147497900
  • 929 + 2147496971 = 2147497900

Showing the first eight; more decompositions exist.
