Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747578, here are decompositions:

  • 5 + 8747573 = 8747578
  • 17 + 8747561 = 8747578
  • 89 + 8747489 = 8747578
  • 107 + 8747471 = 8747578
  • 137 + 8747441 = 8747578
  • 197 + 8747381 = 8747578
  • 251 + 8747327 = 8747578
  • 317 + 8747261 = 8747578

Showing the first eight; more decompositions exist.
