Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497382, here are decompositions:

  • 61 + 2147497321 = 2147497382
  • 139 + 2147497243 = 2147497382
  • 181 + 2147497201 = 2147497382
  • 241 + 2147497141 = 2147497382
  • 421 + 2147496961 = 2147497382
  • 523 + 2147496859 = 2147497382
  • 631 + 2147496751 = 2147497382
  • 1033 + 2147496349 = 2147497382

Showing the first eight; more decompositions exist.
