Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143190, here are decompositions:
- 13 + 143177 = 143190
- 31 + 143159 = 143190
- 53 + 143137 = 143190
- 79 + 143111 = 143190
- 83 + 143107 = 143190
- 97 + 143093 = 143190
- 127 + 143063 = 143190
- 137 + 143053 = 143190
Showing the first eight; more decompositions exist.
