Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622878, here are decompositions:

  • 7 + 8622871 = 8622878
  • 31 + 8622847 = 8622878
  • 37 + 8622841 = 8622878
  • 67 + 8622811 = 8622878
  • 97 + 8622781 = 8622878
  • 157 + 8622721 = 8622878
  • 349 + 8622529 = 8622878
  • 367 + 8622511 = 8622878

Showing the first eight; more decompositions exist.
