Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640202, here are decompositions:

  • 5 + 8640197 = 8640202
  • 41 + 8640161 = 8640202
  • 251 + 8639951 = 8640202
  • 281 + 8639921 = 8640202
  • 293 + 8639909 = 8640202
  • 353 + 8639849 = 8640202
  • 383 + 8639819 = 8640202
  • 449 + 8639753 = 8640202

Showing the first eight; more decompositions exist.
