Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718942, here are decompositions:

  • 61 + 8718881 = 8718942
  • 73 + 8718869 = 8718942
  • 83 + 8718859 = 8718942
  • 103 + 8718839 = 8718942
  • 109 + 8718833 = 8718942
  • 131 + 8718811 = 8718942
  • 139 + 8718803 = 8718942
  • 149 + 8718793 = 8718942

Showing the first eight; more decompositions exist.
