Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4542, here are decompositions:
- 19 + 4523 = 4542
- 23 + 4519 = 4542
- 29 + 4513 = 4542
- 59 + 4483 = 4542
- 61 + 4481 = 4542
- 79 + 4463 = 4542
- 101 + 4441 = 4542
- 151 + 4391 = 4542
Showing the first eight; more decompositions exist.
