Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444848, here are decompositions:

  • 5 + 31444843 = 31444848
  • 11 + 31444837 = 31444848
  • 41 + 31444807 = 31444848
  • 47 + 31444801 = 31444848
  • 59 + 31444789 = 31444848
  • 89 + 31444759 = 31444848
  • 131 + 31444717 = 31444848
  • 157 + 31444691 = 31444848

Showing the first eight; more decompositions exist.
