Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153744, here are decompositions:
- 5 + 153739 = 153744
- 11 + 153733 = 153744
- 43 + 153701 = 153744
- 103 + 153641 = 153744
- 137 + 153607 = 153744
- 181 + 153563 = 153744
- 211 + 153533 = 153744
- 223 + 153521 = 153744
Showing the first eight; more decompositions exist.
