Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544976, here are decompositions:

  • 7 + 31544969 = 31544976
  • 13 + 31544963 = 31544976
  • 53 + 31544923 = 31544976
  • 97 + 31544879 = 31544976
  • 149 + 31544827 = 31544976
  • 157 + 31544819 = 31544976
  • 193 + 31544783 = 31544976
  • 227 + 31544749 = 31544976

Showing the first eight; more decompositions exist.
