Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947842, here are decompositions:

  • 23 + 947819 = 947842
  • 59 + 947783 = 947842
  • 89 + 947753 = 947842
  • 101 + 947741 = 947842
  • 113 + 947729 = 947842
  • 131 + 947711 = 947842
  • 191 + 947651 = 947842
  • 239 + 947603 = 947842

Showing the first eight; more decompositions exist.
