Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122148, here are decompositions:
- 17 + 122131 = 122148
- 31 + 122117 = 122148
- 67 + 122081 = 122148
- 79 + 122069 = 122148
- 97 + 122051 = 122148
- 107 + 122041 = 122148
- 109 + 122039 = 122148
- 127 + 122021 = 122148
Showing the first eight; more decompositions exist.
