Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624308, here are decompositions:

  • 31 + 31624277 = 31624308
  • 167 + 31624141 = 31624308
  • 179 + 31624129 = 31624308
  • 181 + 31624127 = 31624308
  • 239 + 31624069 = 31624308
  • 307 + 31624001 = 31624308
  • 337 + 31623971 = 31624308
  • 349 + 31623959 = 31624308

Showing the first eight; more decompositions exist.
