Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148138, here are decompositions:
- 47 + 148091 = 148138
- 59 + 148079 = 148138
- 257 + 147881 = 148138
- 311 + 147827 = 148138
- 359 + 147779 = 148138
- 449 + 147689 = 148138
- 467 + 147671 = 148138
- 491 + 147647 = 148138
Showing the first eight; more decompositions exist.
