Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43478, here are decompositions:

  • 37 + 43441 = 43478
  • 67 + 43411 = 43478
  • 79 + 43399 = 43478
  • 157 + 43321 = 43478
  • 241 + 43237 = 43478
  • 271 + 43207 = 43478
  • 277 + 43201 = 43478
  • 499 + 42979 = 43478

Showing the first eight; more decompositions exist.
