Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177578, here are decompositions:

  • 67 + 177511 = 177578
  • 97 + 177481 = 177578
  • 151 + 177427 = 177578
  • 157 + 177421 = 177578
  • 199 + 177379 = 177578
  • 241 + 177337 = 177578
  • 277 + 177301 = 177578
  • 367 + 177211 = 177578

Showing the first eight; more decompositions exist.
