Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143184, here are decompositions:
- 7 + 143177 = 143184
- 43 + 143141 = 143184
- 47 + 143137 = 143184
- 71 + 143113 = 143184
- 73 + 143111 = 143184
- 131 + 143053 = 143184
- 191 + 142993 = 143184
- 211 + 142973 = 143184
Showing the first eight; more decompositions exist.
