Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497444, here are decompositions:

  • 41 + 2147497403 = 2147497444
  • 83 + 2147497361 = 2147497444
  • 311 + 2147497133 = 2147497444
  • 401 + 2147497043 = 2147497444
  • 503 + 2147496941 = 2147497444
  • 821 + 2147496623 = 2147497444
  • 887 + 2147496557 = 2147497444
  • 1013 + 2147496431 = 2147497444

Showing the first eight; more decompositions exist.
