Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690178, here are decompositions:

  • 5 + 8690173 = 8690178
  • 59 + 8690119 = 8690178
  • 61 + 8690117 = 8690178
  • 89 + 8690089 = 8690178
  • 109 + 8690069 = 8690178
  • 137 + 8690041 = 8690178
  • 181 + 8689997 = 8690178
  • 191 + 8689987 = 8690178

Showing the first eight; more decompositions exist.
