Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149918, here are decompositions:
- 7 + 149911 = 149918
- 19 + 149899 = 149918
- 79 + 149839 = 149918
- 127 + 149791 = 149918
- 151 + 149767 = 149918
- 229 + 149689 = 149918
- 367 + 149551 = 149918
- 397 + 149521 = 149918
Showing the first eight; more decompositions exist.
