Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528842, here are decompositions:

  • 11 + 31528831 = 31528842
  • 19 + 31528823 = 31528842
  • 29 + 31528813 = 31528842
  • 31 + 31528811 = 31528842
  • 41 + 31528801 = 31528842
  • 101 + 31528741 = 31528842
  • 113 + 31528729 = 31528842
  • 173 + 31528669 = 31528842

Showing the first eight; more decompositions exist.
