Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77472, here are decompositions:

  • 41 + 77431 = 77472
  • 53 + 77419 = 77472
  • 89 + 77383 = 77472
  • 103 + 77369 = 77472
  • 113 + 77359 = 77472
  • 149 + 77323 = 77472
  • 181 + 77291 = 77472
  • 193 + 77279 = 77472

Showing the first eight; more decompositions exist.
