Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75178, here are decompositions:

  • 11 + 75167 = 75178
  • 17 + 75161 = 75178
  • 29 + 75149 = 75178
  • 137 + 75041 = 75178
  • 149 + 75029 = 75178
  • 167 + 75011 = 75178
  • 281 + 74897 = 75178
  • 317 + 74861 = 75178

Showing the first eight; more decompositions exist.
