Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148320, here are decompositions:
- 17 + 148303 = 148320
- 19 + 148301 = 148320
- 41 + 148279 = 148320
- 71 + 148249 = 148320
- 113 + 148207 = 148320
- 127 + 148193 = 148320
- 149 + 148171 = 148320
- 163 + 148157 = 148320
Showing the first eight; more decompositions exist.
