Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460100, here are decompositions:

  • 37 + 31460063 = 31460100
  • 47 + 31460053 = 31460100
  • 83 + 31460017 = 31460100
  • 101 + 31459999 = 31460100
  • 107 + 31459993 = 31460100
  • 137 + 31459963 = 31460100
  • 151 + 31459949 = 31460100
  • 163 + 31459937 = 31460100

Showing the first eight; more decompositions exist.
