Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99280, here are decompositions:

  • 3 + 99277 = 99280
  • 23 + 99257 = 99280
  • 29 + 99251 = 99280
  • 47 + 99233 = 99280
  • 89 + 99191 = 99280
  • 107 + 99173 = 99280
  • 131 + 99149 = 99280
  • 149 + 99131 = 99280

Showing the first eight; more decompositions exist.
