Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147396570, here are decompositions:

  • 13 + 2147396557 = 2147396570
  • 37 + 2147396533 = 2147396570
  • 157 + 2147396413 = 2147396570
  • 229 + 2147396341 = 2147396570
  • 367 + 2147396203 = 2147396570
  • 601 + 2147395969 = 2147396570
  • 643 + 2147395927 = 2147396570
  • 919 + 2147395651 = 2147396570

Showing the first eight; more decompositions exist.
