Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19444, here are decompositions:

  • 3 + 19441 = 19444
  • 11 + 19433 = 19444
  • 17 + 19427 = 19444
  • 23 + 19421 = 19444
  • 41 + 19403 = 19444
  • 53 + 19391 = 19444
  • 71 + 19373 = 19444
  • 233 + 19211 = 19444

Showing the first eight; more decompositions exist.
