Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87474, here are decompositions:

  • 31 + 87443 = 87474
  • 41 + 87433 = 87474
  • 47 + 87427 = 87474
  • 53 + 87421 = 87474
  • 67 + 87407 = 87474
  • 71 + 87403 = 87474
  • 137 + 87337 = 87474
  • 151 + 87323 = 87474

Showing the first eight; more decompositions exist.
