Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748380, here are decompositions:

  • 13 + 8748367 = 8748380
  • 19 + 8748361 = 8748380
  • 103 + 8748277 = 8748380
  • 181 + 8748199 = 8748380
  • 271 + 8748109 = 8748380
  • 283 + 8748097 = 8748380
  • 337 + 8748043 = 8748380
  • 349 + 8748031 = 8748380

Showing the first eight; more decompositions exist.
