Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739940, here are decompositions:

  • 3 + 8739937 = 8739940
  • 23 + 8739917 = 8739940
  • 29 + 8739911 = 8739940
  • 71 + 8739869 = 8739940
  • 89 + 8739851 = 8739940
  • 113 + 8739827 = 8739940
  • 137 + 8739803 = 8739940
  • 173 + 8739767 = 8739940

Showing the first eight; more decompositions exist.
