Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532208, here are decompositions:

  • 5 + 31532203 = 31532208
  • 41 + 31532167 = 31532208
  • 67 + 31532141 = 31532208
  • 137 + 31532071 = 31532208
  • 241 + 31531967 = 31532208
  • 277 + 31531931 = 31532208
  • 457 + 31531751 = 31532208
  • 541 + 31531667 = 31532208

Showing the first eight; more decompositions exist.
