Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738820, here are decompositions:

  • 7 + 8738813 = 8738820
  • 11 + 8738809 = 8738820
  • 19 + 8738801 = 8738820
  • 37 + 8738783 = 8738820
  • 53 + 8738767 = 8738820
  • 61 + 8738759 = 8738820
  • 107 + 8738713 = 8738820
  • 109 + 8738711 = 8738820

Showing the first eight; more decompositions exist.
