Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144542, here are decompositions:
- 3 + 144539 = 144542
- 31 + 144511 = 144542
- 61 + 144481 = 144542
- 103 + 144439 = 144542
- 163 + 144379 = 144542
- 193 + 144349 = 144542
- 271 + 144271 = 144542
- 283 + 144259 = 144542
Showing the first eight; more decompositions exist.
