Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78194, here are decompositions:

  • 3 + 78191 = 78194
  • 31 + 78163 = 78194
  • 37 + 78157 = 78194
  • 73 + 78121 = 78194
  • 163 + 78031 = 78194
  • 211 + 77983 = 78194
  • 331 + 77863 = 78194
  • 397 + 77797 = 78194

Showing the first eight; more decompositions exist.
