Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467242, here are decompositions:

  • 23 + 2147467219 = 2147467242
  • 31 + 2147467211 = 2147467242
  • 73 + 2147467169 = 2147467242
  • 79 + 2147467163 = 2147467242
  • 149 + 2147467093 = 2147467242
  • 199 + 2147467043 = 2147467242
  • 233 + 2147467009 = 2147467242
  • 251 + 2147466991 = 2147467242

Showing the first eight; more decompositions exist.
