Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681370, here are decompositions:

  • 7 + 8681363 = 8681370
  • 11 + 8681359 = 8681370
  • 13 + 8681357 = 8681370
  • 29 + 8681341 = 8681370
  • 53 + 8681317 = 8681370
  • 59 + 8681311 = 8681370
  • 79 + 8681291 = 8681370
  • 83 + 8681287 = 8681370

Showing the first eight; more decompositions exist.
