Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149328, here are decompositions:
- 5 + 149323 = 149328
- 19 + 149309 = 149328
- 31 + 149297 = 149328
- 41 + 149287 = 149328
- 59 + 149269 = 149328
- 71 + 149257 = 149328
- 79 + 149249 = 149328
- 89 + 149239 = 149328
Showing the first eight; more decompositions exist.
