Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747580, here are decompositions:

  • 7 + 8747573 = 8747580
  • 19 + 8747561 = 8747580
  • 41 + 8747539 = 8747580
  • 53 + 8747527 = 8747580
  • 67 + 8747513 = 8747580
  • 97 + 8747483 = 8747580
  • 109 + 8747471 = 8747580
  • 139 + 8747441 = 8747580

Showing the first eight; more decompositions exist.
