Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534848, here are decompositions:

  • 17 + 31534831 = 31534848
  • 29 + 31534819 = 31534848
  • 47 + 31534801 = 31534848
  • 61 + 31534787 = 31534848
  • 97 + 31534751 = 31534848
  • 109 + 31534739 = 31534848
  • 139 + 31534709 = 31534848
  • 157 + 31534691 = 31534848

Showing the first eight; more decompositions exist.
