Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43156, here are decompositions:
- 5 + 43151 = 43156
- 23 + 43133 = 43156
- 53 + 43103 = 43156
- 89 + 43067 = 43156
- 107 + 43049 = 43156
- 137 + 43019 = 43156
- 167 + 42989 = 43156
- 227 + 42929 = 43156
Showing the first eight; more decompositions exist.
