Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51500, here are decompositions:

  • 13 + 51487 = 51500
  • 19 + 51481 = 51500
  • 61 + 51439 = 51500
  • 73 + 51427 = 51500
  • 79 + 51421 = 51500
  • 139 + 51361 = 51500
  • 151 + 51349 = 51500
  • 157 + 51343 = 51500

Showing the first eight; more decompositions exist.
