Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13802, here are decompositions:
- 3 + 13799 = 13802
- 13 + 13789 = 13802
- 43 + 13759 = 13802
- 73 + 13729 = 13802
- 79 + 13723 = 13802
- 109 + 13693 = 13802
- 211 + 13591 = 13802
- 421 + 13381 = 13802
Showing the first eight; more decompositions exist.
