Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78570, here are decompositions:

  • 17 + 78553 = 78570
  • 29 + 78541 = 78570
  • 31 + 78539 = 78570
  • 53 + 78517 = 78570
  • 59 + 78511 = 78570
  • 61 + 78509 = 78570
  • 73 + 78497 = 78570
  • 83 + 78487 = 78570

Showing the first eight; more decompositions exist.
