Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162042, here are decompositions:

  • 31 + 162011 = 162042
  • 43 + 161999 = 162042
  • 59 + 161983 = 162042
  • 71 + 161971 = 162042
  • 73 + 161969 = 162042
  • 131 + 161911 = 162042
  • 163 + 161879 = 162042
  • 173 + 161869 = 162042

Showing the first eight; more decompositions exist.
