Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739438, here are decompositions:

  • 5 + 8739433 = 8739438
  • 7 + 8739431 = 8739438
  • 41 + 8739397 = 8739438
  • 47 + 8739391 = 8739438
  • 79 + 8739359 = 8739438
  • 89 + 8739349 = 8739438
  • 101 + 8739337 = 8739438
  • 107 + 8739331 = 8739438

Showing the first eight; more decompositions exist.
