Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497238, here are decompositions:

  • 37 + 2147497201 = 2147497238
  • 97 + 2147497141 = 2147497238
  • 157 + 2147497081 = 2147497238
  • 199 + 2147497039 = 2147497238
  • 241 + 2147496997 = 2147497238
  • 277 + 2147496961 = 2147497238
  • 379 + 2147496859 = 2147497238
  • 409 + 2147496829 = 2147497238

Showing the first eight; more decompositions exist.
