Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452000, here are decompositions:

  • 7 + 31451993 = 31452000
  • 31 + 31451969 = 31452000
  • 71 + 31451929 = 31452000
  • 131 + 31451869 = 31452000
  • 163 + 31451837 = 31452000
  • 193 + 31451807 = 31452000
  • 199 + 31451801 = 31452000
  • 269 + 31451731 = 31452000

Showing the first eight; more decompositions exist.
