Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615906, here are decompositions:

  • 73 + 8615833 = 8615906
  • 97 + 8615809 = 8615906
  • 139 + 8615767 = 8615906
  • 157 + 8615749 = 8615906
  • 199 + 8615707 = 8615906
  • 283 + 8615623 = 8615906
  • 367 + 8615539 = 8615906
  • 379 + 8615527 = 8615906

Showing the first eight; more decompositions exist.
