Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989938, here are decompositions:

  • 17 + 989921 = 989938
  • 29 + 989909 = 989938
  • 101 + 989837 = 989938
  • 107 + 989831 = 989938
  • 251 + 989687 = 989938
  • 359 + 989579 = 989938
  • 431 + 989507 = 989938
  • 461 + 989477 = 989938

Showing the first eight; more decompositions exist.
