Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526194, here are decompositions:

  • 3 + 31526191 = 31526194
  • 5 + 31526189 = 31526194
  • 53 + 31526141 = 31526194
  • 107 + 31526087 = 31526194
  • 131 + 31526063 = 31526194
  • 137 + 31526057 = 31526194
  • 173 + 31526021 = 31526194
  • 281 + 31525913 = 31526194

Showing the first eight; more decompositions exist.
