Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6156, here are decompositions:
- 5 + 6151 = 6156
- 13 + 6143 = 6156
- 23 + 6133 = 6156
- 43 + 6113 = 6156
- 67 + 6089 = 6156
- 83 + 6073 = 6156
- 89 + 6067 = 6156
- 103 + 6053 = 6156
Showing the first eight; more decompositions exist.
