Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295072940, here are decompositions:

  • 43 + 4295072897 = 4295072940
  • 61 + 4295072879 = 4295072940
  • 73 + 4295072867 = 4295072940
  • 79 + 4295072861 = 4295072940
  • 83 + 4295072857 = 4295072940
  • 113 + 4295072827 = 4295072940
  • 131 + 4295072809 = 4295072940
  • 139 + 4295072801 = 4295072940

Showing the first eight; more decompositions exist.
