Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11542, here are decompositions:
- 23 + 11519 = 11542
- 53 + 11489 = 11542
- 59 + 11483 = 11542
- 71 + 11471 = 11542
- 131 + 11411 = 11542
- 149 + 11393 = 11542
- 173 + 11369 = 11542
- 191 + 11351 = 11542
Showing the first eight; more decompositions exist.
