Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947830, here are decompositions:

  • 11 + 947819 = 947830
  • 47 + 947783 = 947830
  • 83 + 947747 = 947830
  • 89 + 947741 = 947830
  • 101 + 947729 = 947830
  • 179 + 947651 = 947830
  • 227 + 947603 = 947830
  • 251 + 947579 = 947830

Showing the first eight; more decompositions exist.
