Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20696, here are decompositions:

  • 3 + 20693 = 20696
  • 97 + 20599 = 20696
  • 103 + 20593 = 20696
  • 163 + 20533 = 20696
  • 307 + 20389 = 20696
  • 337 + 20359 = 20696
  • 349 + 20347 = 20696
  • 373 + 20323 = 20696

Showing the first eight; more decompositions exist.
