Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78200, here are decompositions:

  • 7 + 78193 = 78200
  • 37 + 78163 = 78200
  • 43 + 78157 = 78200
  • 61 + 78139 = 78200
  • 79 + 78121 = 78200
  • 151 + 78049 = 78200
  • 193 + 78007 = 78200
  • 223 + 77977 = 78200

Showing the first eight; more decompositions exist.
