Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149984, here are decompositions:
- 13 + 149971 = 149984
- 31 + 149953 = 149984
- 73 + 149911 = 149984
- 157 + 149827 = 149984
- 181 + 149803 = 149984
- 193 + 149791 = 149984
- 271 + 149713 = 149984
- 421 + 149563 = 149984
Showing the first eight; more decompositions exist.
