Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77528, here are decompositions:

  • 7 + 77521 = 77528
  • 19 + 77509 = 77528
  • 37 + 77491 = 77528
  • 97 + 77431 = 77528
  • 109 + 77419 = 77528
  • 151 + 77377 = 77528
  • 181 + 77347 = 77528
  • 211 + 77317 = 77528

Showing the first eight; more decompositions exist.
