Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584100, here are decompositions:

  • 31 + 2147584069 = 2147584100
  • 37 + 2147584063 = 2147584100
  • 43 + 2147584057 = 2147584100
  • 139 + 2147583961 = 2147584100
  • 157 + 2147583943 = 2147584100
  • 163 + 2147583937 = 2147584100
  • 271 + 2147583829 = 2147584100
  • 307 + 2147583793 = 2147584100

Showing the first eight; more decompositions exist.
