Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738580, here are decompositions:

  • 13 + 8738567 = 8738580
  • 41 + 8738539 = 8738580
  • 47 + 8738533 = 8738580
  • 73 + 8738507 = 8738580
  • 89 + 8738491 = 8738580
  • 107 + 8738473 = 8738580
  • 131 + 8738449 = 8738580
  • 173 + 8738407 = 8738580

Showing the first eight; more decompositions exist.
