Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4156, here are decompositions:
- 3 + 4153 = 4156
- 17 + 4139 = 4156
- 23 + 4133 = 4156
- 29 + 4127 = 4156
- 83 + 4073 = 4156
- 107 + 4049 = 4156
- 137 + 4019 = 4156
- 149 + 4007 = 4156
Showing the first eight; more decompositions exist.
