Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473154, here are decompositions:

  • 3 + 2147473151 = 2147473154
  • 37 + 2147473117 = 2147473154
  • 271 + 2147472883 = 2147473154
  • 367 + 2147472787 = 2147473154
  • 397 + 2147472757 = 2147473154
  • 457 + 2147472697 = 2147473154
  • 733 + 2147472421 = 2147473154
  • 811 + 2147472343 = 2147473154

Showing the first eight; more decompositions exist.
