Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747586, here are decompositions:

  • 7 + 8747579 = 8747586
  • 13 + 8747573 = 8747586
  • 47 + 8747539 = 8747586
  • 59 + 8747527 = 8747586
  • 73 + 8747513 = 8747586
  • 97 + 8747489 = 8747586
  • 103 + 8747483 = 8747586
  • 163 + 8747423 = 8747586

Showing the first eight; more decompositions exist.
