Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143542, here are decompositions:
- 5 + 143537 = 143542
- 23 + 143519 = 143542
- 29 + 143513 = 143542
- 41 + 143501 = 143542
- 53 + 143489 = 143542
- 59 + 143483 = 143542
- 251 + 143291 = 143542
- 281 + 143261 = 143542
Showing the first eight; more decompositions exist.
