Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646530, here are decompositions:

  • 19 + 8646511 = 8646530
  • 43 + 8646487 = 8646530
  • 73 + 8646457 = 8646530
  • 127 + 8646403 = 8646530
  • 271 + 8646259 = 8646530
  • 283 + 8646247 = 8646530
  • 307 + 8646223 = 8646530
  • 349 + 8646181 = 8646530

Showing the first eight; more decompositions exist.
