Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497242, here are decompositions:

  • 5 + 2147497237 = 2147497242
  • 41 + 2147497201 = 2147497242
  • 101 + 2147497141 = 2147497242
  • 109 + 2147497133 = 2147497242
  • 199 + 2147497043 = 2147497242
  • 223 + 2147497019 = 2147497242
  • 263 + 2147496979 = 2147497242
  • 271 + 2147496971 = 2147497242

Showing the first eight; more decompositions exist.
