Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677280, here are decompositions:

  • 13 + 8677267 = 8677280
  • 19 + 8677261 = 8677280
  • 109 + 8677171 = 8677280
  • 223 + 8677057 = 8677280
  • 229 + 8677051 = 8677280
  • 307 + 8676973 = 8677280
  • 331 + 8676949 = 8677280
  • 397 + 8676883 = 8677280

Showing the first eight; more decompositions exist.
