Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690684, here are decompositions:

  • 7 + 8690677 = 8690684
  • 73 + 8690611 = 8690684
  • 127 + 8690557 = 8690684
  • 271 + 8690413 = 8690684
  • 307 + 8690377 = 8690684
  • 313 + 8690371 = 8690684
  • 367 + 8690317 = 8690684
  • 463 + 8690221 = 8690684

Showing the first eight; more decompositions exist.
