Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468186, here are decompositions:

  • 13 + 2147468173 = 2147468186
  • 67 + 2147468119 = 2147468186
  • 223 + 2147467963 = 2147468186
  • 373 + 2147467813 = 2147468186
  • 439 + 2147467747 = 2147468186
  • 547 + 2147467639 = 2147468186
  • 607 + 2147467579 = 2147468186
  • 859 + 2147467327 = 2147468186

Showing the first eight; more decompositions exist.
