Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465290, here are decompositions:

  • 23 + 2147465267 = 2147465290
  • 101 + 2147465189 = 2147465290
  • 137 + 2147465153 = 2147465290
  • 281 + 2147465009 = 2147465290
  • 449 + 2147464841 = 2147465290
  • 701 + 2147464589 = 2147465290
  • 881 + 2147464409 = 2147465290
  • 953 + 2147464337 = 2147465290

Showing the first eight; more decompositions exist.
