Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3156, here are decompositions:
- 19 + 3137 = 3156
- 37 + 3119 = 3156
- 47 + 3109 = 3156
- 67 + 3089 = 3156
- 73 + 3083 = 3156
- 89 + 3067 = 3156
- 107 + 3049 = 3156
- 137 + 3019 = 3156
Showing the first eight; more decompositions exist.
