Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123148, here are decompositions:
- 5 + 123143 = 123148
- 71 + 123077 = 123148
- 89 + 123059 = 123148
- 131 + 123017 = 123148
- 191 + 122957 = 123148
- 227 + 122921 = 123148
- 257 + 122891 = 123148
- 281 + 122867 = 123148
Showing the first eight; more decompositions exist.
