Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747028, here are decompositions:

  • 29 + 8746999 = 8747028
  • 61 + 8746967 = 8747028
  • 71 + 8746957 = 8747028
  • 79 + 8746949 = 8747028
  • 89 + 8746939 = 8747028
  • 107 + 8746921 = 8747028
  • 109 + 8746919 = 8747028
  • 149 + 8746879 = 8747028

Showing the first eight; more decompositions exist.
