Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45538, here are decompositions:

  • 5 + 45533 = 45538
  • 41 + 45497 = 45538
  • 47 + 45491 = 45538
  • 149 + 45389 = 45538
  • 197 + 45341 = 45538
  • 257 + 45281 = 45538
  • 347 + 45191 = 45538
  • 359 + 45179 = 45538

Showing the first eight; more decompositions exist.
