Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497654, here are decompositions:

  • 83 + 2147497571 = 2147497654
  • 131 + 2147497523 = 2147497654
  • 173 + 2147497481 = 2147497654
  • 251 + 2147497403 = 2147497654
  • 293 + 2147497361 = 2147497654
  • 521 + 2147497133 = 2147497654
  • 683 + 2147496971 = 2147497654
  • 941 + 2147496713 = 2147497654

Showing the first eight; more decompositions exist.
