Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78572, here are decompositions:

  • 3 + 78569 = 78572
  • 19 + 78553 = 78572
  • 31 + 78541 = 78572
  • 61 + 78511 = 78572
  • 271 + 78301 = 78572
  • 313 + 78259 = 78572
  • 331 + 78241 = 78572
  • 379 + 78193 = 78572

Showing the first eight; more decompositions exist.
