Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294990242, here are decompositions:

  • 71 + 4294990171 = 4294990242
  • 113 + 4294990129 = 4294990242
  • 163 + 4294990079 = 4294990242
  • 239 + 4294990003 = 4294990242
  • 271 + 4294989971 = 4294990242
  • 293 + 4294989949 = 4294990242
  • 359 + 4294989883 = 4294990242
  • 443 + 4294989799 = 4294990242

Showing the first eight; more decompositions exist.
