Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481104, here are decompositions:

  • 3 + 31481101 = 31481104
  • 47 + 31481057 = 31481104
  • 131 + 31480973 = 31481104
  • 191 + 31480913 = 31481104
  • 311 + 31480793 = 31481104
  • 1013 + 31480091 = 31481104
  • 1223 + 31479881 = 31481104
  • 1283 + 31479821 = 31481104

Showing the first eight; more decompositions exist.
