Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147523242, here are decompositions:

  • 13 + 2147523229 = 2147523242
  • 19 + 2147523223 = 2147523242
  • 31 + 2147523211 = 2147523242
  • 43 + 2147523199 = 2147523242
  • 79 + 2147523163 = 2147523242
  • 283 + 2147522959 = 2147523242
  • 313 + 2147522929 = 2147523242
  • 373 + 2147522869 = 2147523242

Showing the first eight; more decompositions exist.
