Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724874, here are decompositions:

  • 3 + 8724871 = 8724874
  • 47 + 8724827 = 8724874
  • 71 + 8724803 = 8724874
  • 233 + 8724641 = 8724874
  • 503 + 8724371 = 8724874
  • 563 + 8724311 = 8724874
  • 773 + 8724101 = 8724874
  • 881 + 8723993 = 8724874

Showing the first eight; more decompositions exist.
