Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534130, here are decompositions:

  • 13 + 31534117 = 31534130
  • 73 + 31534057 = 31534130
  • 79 + 31534051 = 31534130
  • 97 + 31534033 = 31534130
  • 151 + 31533979 = 31534130
  • 163 + 31533967 = 31534130
  • 181 + 31533949 = 31534130
  • 211 + 31533919 = 31534130

Showing the first eight; more decompositions exist.
