Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469838, here are decompositions:

  • 179 + 2147469659 = 2147469838
  • 317 + 2147469521 = 2147469838
  • 347 + 2147469491 = 2147469838
  • 389 + 2147469449 = 2147469838
  • 419 + 2147469419 = 2147469838
  • 491 + 2147469347 = 2147469838
  • 509 + 2147469329 = 2147469838
  • 599 + 2147469239 = 2147469838

Showing the first eight; more decompositions exist.
