Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635040, here are decompositions:

  • 19 + 8635021 = 8635040
  • 79 + 8634961 = 8635040
  • 151 + 8634889 = 8635040
  • 157 + 8634883 = 8635040
  • 181 + 8634859 = 8635040
  • 199 + 8634841 = 8635040
  • 229 + 8634811 = 8635040
  • 373 + 8634667 = 8635040

Showing the first eight; more decompositions exist.
