Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724764, here are decompositions:

  • 43 + 8724721 = 8724764
  • 67 + 8724697 = 8724764
  • 163 + 8724601 = 8724764
  • 271 + 8724493 = 8724764
  • 277 + 8724487 = 8724764
  • 463 + 8724301 = 8724764
  • 523 + 8724241 = 8724764
  • 541 + 8724223 = 8724764

Showing the first eight; more decompositions exist.
