Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472230, here are decompositions:

  • 31 + 2147472199 = 2147472230
  • 97 + 2147472133 = 2147472230
  • 139 + 2147472091 = 2147472230
  • 193 + 2147472037 = 2147472230
  • 349 + 2147471881 = 2147472230
  • 367 + 2147471863 = 2147472230
  • 523 + 2147471707 = 2147472230
  • 601 + 2147471629 = 2147472230

Showing the first eight; more decompositions exist.
