Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478842, here are decompositions:

  • 11 + 478831 = 478842
  • 19 + 478823 = 478842
  • 29 + 478813 = 478842
  • 31 + 478811 = 478842
  • 41 + 478801 = 478842
  • 73 + 478769 = 478842
  • 79 + 478763 = 478842
  • 101 + 478741 = 478842

Showing the first eight; more decompositions exist.
