Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578778, here are decompositions:

  • 37 + 578741 = 578778
  • 59 + 578719 = 578778
  • 89 + 578689 = 578778
  • 131 + 578647 = 578778
  • 157 + 578621 = 578778
  • 181 + 578597 = 578778
  • 191 + 578587 = 578778
  • 197 + 578581 = 578778

Showing the first eight; more decompositions exist.
