Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526988, here are decompositions:

  • 47 + 31526941 = 31526988
  • 61 + 31526927 = 31526988
  • 67 + 31526921 = 31526988
  • 89 + 31526899 = 31526988
  • 107 + 31526881 = 31526988
  • 109 + 31526879 = 31526988
  • 179 + 31526809 = 31526988
  • 197 + 31526791 = 31526988

Showing the first eight; more decompositions exist.
