Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615712, here are decompositions:

  • 5 + 8615707 = 8615712
  • 19 + 8615693 = 8615712
  • 59 + 8615653 = 8615712
  • 89 + 8615623 = 8615712
  • 173 + 8615539 = 8615712
  • 199 + 8615513 = 8615712
  • 233 + 8615479 = 8615712
  • 239 + 8615473 = 8615712

Showing the first eight; more decompositions exist.
