Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548650, here are decompositions:

  • 31 + 31548619 = 31548650
  • 37 + 31548613 = 31548650
  • 73 + 31548577 = 31548650
  • 103 + 31548547 = 31548650
  • 151 + 31548499 = 31548650
  • 223 + 31548427 = 31548650
  • 307 + 31548343 = 31548650
  • 337 + 31548313 = 31548650

Showing the first eight; more decompositions exist.
