Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149256, here are decompositions:
- 5 + 149251 = 149256
- 7 + 149249 = 149256
- 17 + 149239 = 149256
- 43 + 149213 = 149256
- 59 + 149197 = 149256
- 73 + 149183 = 149256
- 83 + 149173 = 149256
- 97 + 149159 = 149256
Showing the first eight; more decompositions exist.
