Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623300, here are decompositions:

  • 43 + 31623257 = 31623300
  • 89 + 31623211 = 31623300
  • 101 + 31623199 = 31623300
  • 127 + 31623173 = 31623300
  • 131 + 31623169 = 31623300
  • 179 + 31623121 = 31623300
  • 239 + 31623061 = 31623300
  • 277 + 31623023 = 31623300

Showing the first eight; more decompositions exist.
