Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615858, here are decompositions:

  • 67 + 8615791 = 8615858
  • 109 + 8615749 = 8615858
  • 151 + 8615707 = 8615858
  • 271 + 8615587 = 8615858
  • 331 + 8615527 = 8615858
  • 367 + 8615491 = 8615858
  • 379 + 8615479 = 8615858
  • 397 + 8615461 = 8615858

Showing the first eight; more decompositions exist.
