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.
