Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978770, here are decompositions:

  • 43 + 978727 = 978770
  • 73 + 978697 = 978770
  • 127 + 978643 = 978770
  • 151 + 978619 = 978770
  • 229 + 978541 = 978770
  • 307 + 978463 = 978770
  • 313 + 978457 = 978770
  • 367 + 978403 = 978770

Showing the first eight; more decompositions exist.
