Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615558, here are decompositions:

  • 19 + 8615539 = 8615558
  • 31 + 8615527 = 8615558
  • 67 + 8615491 = 8615558
  • 79 + 8615479 = 8615558
  • 97 + 8615461 = 8615558
  • 181 + 8615377 = 8615558
  • 271 + 8615287 = 8615558
  • 397 + 8615161 = 8615558

Showing the first eight; more decompositions exist.
