Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147543318, here are decompositions:

  • 7 + 2147543311 = 2147543318
  • 31 + 2147543287 = 2147543318
  • 181 + 2147543137 = 2147543318
  • 409 + 2147542909 = 2147543318
  • 421 + 2147542897 = 2147543318
  • 439 + 2147542879 = 2147543318
  • 499 + 2147542819 = 2147543318
  • 691 + 2147542627 = 2147543318

Showing the first eight; more decompositions exist.
