Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497402, here are decompositions:

  • 41 + 2147497361 = 2147497402
  • 53 + 2147497349 = 2147497402
  • 269 + 2147497133 = 2147497402
  • 359 + 2147497043 = 2147497402
  • 383 + 2147497019 = 2147497402
  • 431 + 2147496971 = 2147497402
  • 461 + 2147496941 = 2147497402
  • 563 + 2147496839 = 2147497402

Showing the first eight; more decompositions exist.
