Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467378, here are decompositions:

  • 11 + 2147467367 = 2147467378
  • 47 + 2147467331 = 2147467378
  • 167 + 2147467211 = 2147467378
  • 257 + 2147467121 = 2147467378
  • 311 + 2147467067 = 2147467378
  • 431 + 2147466947 = 2147467378
  • 509 + 2147466869 = 2147467378
  • 677 + 2147466701 = 2147467378

Showing the first eight; more decompositions exist.
