Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147373998, here are decompositions:

  • 19 + 2147373979 = 2147373998
  • 31 + 2147373967 = 2147373998
  • 37 + 2147373961 = 2147373998
  • 67 + 2147373931 = 2147373998
  • 337 + 2147373661 = 2147373998
  • 409 + 2147373589 = 2147373998
  • 487 + 2147373511 = 2147373998
  • 541 + 2147373457 = 2147373998

Showing the first eight; more decompositions exist.
