Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72500, here are decompositions:

  • 3 + 72497 = 72500
  • 7 + 72493 = 72500
  • 19 + 72481 = 72500
  • 31 + 72469 = 72500
  • 79 + 72421 = 72500
  • 163 + 72337 = 72500
  • 193 + 72307 = 72500
  • 223 + 72277 = 72500

Showing the first eight; more decompositions exist.
