Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13156, here are decompositions:
- 5 + 13151 = 13156
- 29 + 13127 = 13156
- 47 + 13109 = 13156
- 53 + 13103 = 13156
- 107 + 13049 = 13156
- 113 + 13043 = 13156
- 149 + 13007 = 13156
- 173 + 12983 = 13156
Showing the first eight; more decompositions exist.
