Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642502, here are decompositions:

  • 13 + 8642489 = 8642502
  • 53 + 8642449 = 8642502
  • 73 + 8642429 = 8642502
  • 173 + 8642329 = 8642502
  • 199 + 8642303 = 8642502
  • 313 + 8642189 = 8642502
  • 383 + 8642119 = 8642502
  • 439 + 8642063 = 8642502

Showing the first eight; more decompositions exist.
