Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947872, here are decompositions:

  • 11 + 947861 = 947872
  • 53 + 947819 = 947872
  • 89 + 947783 = 947872
  • 131 + 947741 = 947872
  • 251 + 947621 = 947872
  • 269 + 947603 = 947872
  • 293 + 947579 = 947872
  • 311 + 947561 = 947872

Showing the first eight; more decompositions exist.
