Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142452, here are decompositions:
- 19 + 142433 = 142452
- 31 + 142421 = 142452
- 61 + 142391 = 142452
- 71 + 142381 = 142452
- 83 + 142369 = 142452
- 181 + 142271 = 142452
- 229 + 142223 = 142452
- 241 + 142211 = 142452
Showing the first eight; more decompositions exist.
