Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497072, here are decompositions:

  • 29 + 2147497043 = 2147497072
  • 53 + 2147497019 = 2147497072
  • 101 + 2147496971 = 2147497072
  • 131 + 2147496941 = 2147497072
  • 233 + 2147496839 = 2147497072
  • 293 + 2147496779 = 2147497072
  • 359 + 2147496713 = 2147497072
  • 419 + 2147496653 = 2147497072

Showing the first eight; more decompositions exist.
