Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551860, here are decompositions:

  • 11 + 551849 = 551860
  • 17 + 551843 = 551860
  • 47 + 551813 = 551860
  • 59 + 551801 = 551860
  • 107 + 551753 = 551860
  • 131 + 551729 = 551860
  • 137 + 551723 = 551860
  • 167 + 551693 = 551860

Showing the first eight; more decompositions exist.
