Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724558, here are decompositions:

  • 47 + 8724511 = 8724558
  • 61 + 8724497 = 8724558
  • 71 + 8724487 = 8724558
  • 79 + 8724479 = 8724558
  • 97 + 8724461 = 8724558
  • 137 + 8724421 = 8724558
  • 181 + 8724377 = 8724558
  • 211 + 8724347 = 8724558

Showing the first eight; more decompositions exist.
