Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149398, here are decompositions:
- 5 + 149393 = 149398
- 17 + 149381 = 149398
- 47 + 149351 = 149398
- 89 + 149309 = 149398
- 101 + 149297 = 149398
- 149 + 149249 = 149398
- 239 + 149159 = 149398
- 311 + 149087 = 149398
Showing the first eight; more decompositions exist.
