Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6578, here are decompositions:

  • 7 + 6571 = 6578
  • 31 + 6547 = 6578
  • 97 + 6481 = 6578
  • 109 + 6469 = 6578
  • 127 + 6451 = 6578
  • 151 + 6427 = 6578
  • 157 + 6421 = 6578
  • 181 + 6397 = 6578

Showing the first eight; more decompositions exist.
