Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295068728, here are decompositions:

  • 7 + 4295068721 = 4295068728
  • 31 + 4295068697 = 4295068728
  • 61 + 4295068667 = 4295068728
  • 127 + 4295068601 = 4295068728
  • 131 + 4295068597 = 4295068728
  • 157 + 4295068571 = 4295068728
  • 277 + 4295068451 = 4295068728
  • 311 + 4295068417 = 4295068728

Showing the first eight; more decompositions exist.
