Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643202, here are decompositions:

  • 3 + 8643199 = 8643202
  • 5 + 8643197 = 8643202
  • 53 + 8643149 = 8643202
  • 59 + 8643143 = 8643202
  • 149 + 8643053 = 8643202
  • 179 + 8643023 = 8643202
  • 251 + 8642951 = 8643202
  • 263 + 8642939 = 8643202

Showing the first eight; more decompositions exist.
