Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17438, here are decompositions:

  • 7 + 17431 = 17438
  • 19 + 17419 = 17438
  • 37 + 17401 = 17438
  • 61 + 17377 = 17438
  • 79 + 17359 = 17438
  • 97 + 17341 = 17438
  • 139 + 17299 = 17438
  • 181 + 17257 = 17438

Showing the first eight; more decompositions exist.
