Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29138, here are decompositions:
- 7 + 29131 = 29138
- 37 + 29101 = 29138
- 61 + 29077 = 29138
- 79 + 29059 = 29138
- 211 + 28927 = 29138
- 229 + 28909 = 29138
- 271 + 28867 = 29138
- 331 + 28807 = 29138
Showing the first eight; more decompositions exist.
