Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147588446, here are decompositions:

  • 137 + 2147588309 = 2147588446
  • 167 + 2147588279 = 2147588446
  • 293 + 2147588153 = 2147588446
  • 347 + 2147588099 = 2147588446
  • 389 + 2147588057 = 2147588446
  • 503 + 2147587943 = 2147588446
  • 587 + 2147587859 = 2147588446
  • 593 + 2147587853 = 2147588446

Showing the first eight; more decompositions exist.
