Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623000, here are decompositions:

  • 41 + 31622959 = 31623000
  • 53 + 31622947 = 31623000
  • 61 + 31622939 = 31623000
  • 67 + 31622933 = 31623000
  • 107 + 31622893 = 31623000
  • 137 + 31622863 = 31623000
  • 163 + 31622837 = 31623000
  • 191 + 31622809 = 31623000

Showing the first eight; more decompositions exist.
