Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722042, here are decompositions:

  • 23 + 8722019 = 8722042
  • 41 + 8722001 = 8722042
  • 53 + 8721989 = 8722042
  • 101 + 8721941 = 8722042
  • 113 + 8721929 = 8722042
  • 191 + 8721851 = 8722042
  • 269 + 8721773 = 8722042
  • 293 + 8721749 = 8722042

Showing the first eight; more decompositions exist.
