Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472368, here are decompositions:

  • 79 + 2147472289 = 2147472368
  • 109 + 2147472259 = 2147472368
  • 277 + 2147472091 = 2147472368
  • 331 + 2147472037 = 2147472368
  • 487 + 2147471881 = 2147472368
  • 661 + 2147471707 = 2147472368
  • 739 + 2147471629 = 2147472368
  • 757 + 2147471611 = 2147472368

Showing the first eight; more decompositions exist.
