Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142562, here are decompositions:
- 3 + 142559 = 142562
- 19 + 142543 = 142562
- 61 + 142501 = 142562
- 109 + 142453 = 142562
- 181 + 142381 = 142562
- 193 + 142369 = 142562
- 331 + 142231 = 142562
- 373 + 142189 = 142562
Showing the first eight; more decompositions exist.
