Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153984, here are decompositions:
- 31 + 153953 = 153984
- 37 + 153947 = 153984
- 43 + 153941 = 153984
- 71 + 153913 = 153984
- 73 + 153911 = 153984
- 97 + 153887 = 153984
- 107 + 153877 = 153984
- 113 + 153871 = 153984
Showing the first eight; more decompositions exist.
