Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19072, here are decompositions:

  • 3 + 19069 = 19072
  • 41 + 19031 = 19072
  • 59 + 19013 = 19072
  • 71 + 19001 = 19072
  • 113 + 18959 = 19072
  • 173 + 18899 = 19072
  • 233 + 18839 = 19072
  • 269 + 18803 = 19072

Showing the first eight; more decompositions exist.
