Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45478, here are decompositions:

  • 89 + 45389 = 45478
  • 101 + 45377 = 45478
  • 137 + 45341 = 45478
  • 149 + 45329 = 45478
  • 197 + 45281 = 45478
  • 281 + 45197 = 45478
  • 317 + 45161 = 45478
  • 347 + 45131 = 45478

Showing the first eight; more decompositions exist.
