Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712500, here are decompositions:

  • 3 + 8712497 = 8712500
  • 79 + 8712421 = 8712500
  • 103 + 8712397 = 8712500
  • 127 + 8712373 = 8712500
  • 151 + 8712349 = 8712500
  • 163 + 8712337 = 8712500
  • 193 + 8712307 = 8712500
  • 241 + 8712259 = 8712500

Showing the first eight; more decompositions exist.
