Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977720, here are decompositions:

  • 109 + 977611 = 977720
  • 127 + 977593 = 977720
  • 181 + 977539 = 977720
  • 199 + 977521 = 977720
  • 283 + 977437 = 977720
  • 307 + 977413 = 977720
  • 313 + 977407 = 977720
  • 397 + 977323 = 977720

Showing the first eight; more decompositions exist.
