Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142526, here are decompositions:
- 73 + 142453 = 142526
- 157 + 142369 = 142526
- 199 + 142327 = 142526
- 229 + 142297 = 142526
- 337 + 142189 = 142526
- 367 + 142159 = 142526
- 487 + 142039 = 142526
- 619 + 141907 = 142526
Showing the first eight; more decompositions exist.
