Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542958, here are decompositions:

  • 17 + 31542941 = 31542958
  • 47 + 31542911 = 31542958
  • 101 + 31542857 = 31542958
  • 131 + 31542827 = 31542958
  • 149 + 31542809 = 31542958
  • 191 + 31542767 = 31542958
  • 281 + 31542677 = 31542958
  • 449 + 31542509 = 31542958

Showing the first eight; more decompositions exist.
