Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747740, here are decompositions:

  • 3 + 8747737 = 8747740
  • 17 + 8747723 = 8747740
  • 137 + 8747603 = 8747740
  • 167 + 8747573 = 8747740
  • 179 + 8747561 = 8747740
  • 227 + 8747513 = 8747740
  • 251 + 8747489 = 8747740
  • 257 + 8747483 = 8747740

Showing the first eight; more decompositions exist.
