Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469684, here are decompositions:

  • 5 + 2147469679 = 2147469684
  • 47 + 2147469637 = 2147469684
  • 131 + 2147469553 = 2147469684
  • 163 + 2147469521 = 2147469684
  • 193 + 2147469491 = 2147469684
  • 263 + 2147469421 = 2147469684
  • 337 + 2147469347 = 2147469684
  • 401 + 2147469283 = 2147469684

Showing the first eight; more decompositions exist.
