Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740580, here are decompositions:

  • 3 + 8740577 = 8740580
  • 19 + 8740561 = 8740580
  • 61 + 8740519 = 8740580
  • 127 + 8740453 = 8740580
  • 151 + 8740429 = 8740580
  • 193 + 8740387 = 8740580
  • 307 + 8740273 = 8740580
  • 397 + 8740183 = 8740580

Showing the first eight; more decompositions exist.
