Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947142, here are decompositions:

  • 5 + 947137 = 947142
  • 13 + 947129 = 947142
  • 23 + 947119 = 947142
  • 59 + 947083 = 947142
  • 109 + 947033 = 947142
  • 149 + 946993 = 947142
  • 173 + 946969 = 947142
  • 181 + 946961 = 947142

Showing the first eight; more decompositions exist.
